We use a novel real-time formulation of the functional renormalization group (FRG) for dynamical systems with reversible mode couplings to study model H, the conjectured dynamic universality class of the quantum chromodynamics (QCD) critical point. We emphasize the structural similarities with model G, conjectured to be the dynamic universality class of the chiral phase transition in the limit of two

We present a systematic diagrammatic investigation of the classical limit of observables computed from scattering amplitudes in quantum field theory through the Kosower-Maybee-O’Connell formalism, motivated by the study of gravitational waves from black hole binaries. We achieve the manifest cancellation of divergences in the ℏ→0 limit at the integrand level beyond one loop by employing the Schwinger

In this paper, we consider hard-wall anti–de Sitter/quantum chromodynamics (AdS/QCD) models extended by a string-theory inspired Chern-Simons action in terms of a superconnection involving a bifundamental scalar field which corresponds to the open-string tachyon of brane-antibrane configurations and which is naturally identified with the holographic dual of the quark condensate in chiral symmetry breaking

Neutrino propagation in the Galactic and extragalactic magnetic fields is considered. We extend an approach developed in [A. Popov and A. Studenikin, Neutrino eigenstates and flavour, spin and spin-flavour oscillations in a constant magnetic field, .] to describe neutrino flavor and spin oscillations using wave packets. The evolution equations for the neutrino wave packets in a uniform and nonuniform

In neutrino experiments sensitive to multiple flavors, the analyzers may be presented with a choice of treating the uncertainties on the respective cross sections in a correlated or an uncorrelated manner. This study focuses on the charged current deep inelastic scattering (CC DIS) channel in experiments sensitive to both muon and tau neutrinos. We evaluate the ratio of the leading-order ντ and νμ

We examine the minimal U(1)Lμ−Lτ gauge model in light of the latest neutrino data, including neutrino oscillations, cosmological observations, direct mass measurements, and neutrinoless double-beta decay. Using the most conservative oscillation data, we find that normal ordering is excluded at approximately the 90% confidence level (CL). Incorporating cosmological constraints from cosmic microwave

We present the implementation of a new interface in 3.0 supporting all diboson and triboson processes with fully leptonic final states, enabling next-to-leading order (NLO)+parton shower (PS) matched calculations. To demonstrate its capabilities, we study parton shower effects in the triboson production process pp→e+νeμ−ν¯μγ+X using erwig 7.3 with NLO QCD amplitudes from 3.0. We estimate uncertainties

We consider the vacuum wave function of a free scalar field theory in space partitioned into two regions, with the field obeying Robin conditions (of parameter κ) on the interface. A direct integration over fields in a subregion is carried out to obtain the reduced density matrix. This leads to a constructive proof of the Reeh-Schlieder theorem. We analyze the entanglement entropy as a function of

The challenges in neutrino-nucleus cross section modeling and its impact on neutrino oscillation experiments are widely recognized. However, a comprehensive and theoretically robust estimation of cross section uncertainties has been lacking, and few studies have quantitatively examined their impact on oscillation measurements. In this work, we evaluate the effect of cross section uncertainties on oscillation

We construct a new dilaton Weyl multiplet for N=3 conformal supergravity in four dimensions. The R-symmetry realized on this dilaton Weyl multiplet is SU(2)×U(1)×U(1). The construction follows a two-step procedure. First, two on-shell vector multiplets are coupled to the standard Weyl multiplet. Second, using the field equations of the vector multiplets, some of the auxiliary fields of the standard

Wave-optics phenomena in gravitational lensing occur when the signal’s wavelength is commensurate to the gravitational radius of the lens. Although potentially detectable in lensed gravitational waves, fast radio bursts and pulsars, accurate numerical predictions are challenging to compute. Here we present novel methods for wave-optics lensing that allow the treatment of general lenses. In addition

We investigate the properties of QCD axion at low temperature and moderate density in the Nambu-Jona-Lasinio model with instanton induced interactions by simultaneously considering the scalar and pseudoscalar condensates in both quark-antiquark and diquark channels. We derive the analytical dispersion relations of quarks with four-type condensates at nonzero theta angle θ=a/fa. The axion mass, quartic

In this paper, we systematically investigate the general spin-1 dark matter–nucleus interactions within the framework of effective field theories (EFTs). We consider both the nonrelativistic (NR) and the relativistic EFT descriptions of the DM interactions with nucleons and quarks. In the NREFT framework, we present a complete list of NR operators for spin-1 DM coupling to nucleons and compute their

We present a novel family of analytical and numerical classical solitonic solutions to the nonlinear equations governing the dynamics of the bosonic part of a supermembrane (M2-brane) mass operator formulated on a flat spacetime toroidally compactified with worldvolume fluxes. The dynamics of membrane excitations is associated with sectors of the supermembrane theory that exhibit a discrete spectrum

Resonant anomaly detection methods have great potential for enhancing the sensitivity of traditional bump hunt searches. A key component of these methods is a high quality background template used to produce an anomaly score. Using the LHC Olympics R&D dataset, we demonstrate that this background template can also be repurposed to directly estimate the background expectation in a simple cut and count

In this paper we proposed the homotopy approach for solving the nonlinear Balitsky-Kovchegov evolution equation with running QCD coupling. The approach consists of two steps. First, is the analytic solution to the nonlinear evolution equation for the simplified, leading twist kernel. Second, is the iteration procedure that allow us to calculate corrections analytically or seminumerically. For the leading

We derive an analytic form of the joint prior of effective spin parameters, χeff and χp, assuming an isotropic and uniform-in-magnitude spin distribution. This is a vital factor in performing hierarchical Bayesian inference for studying the population properties of merging compact binaries observed with gravitational waves. In previous analyses, this was evaluated numerically using kernel density estimation

We demonstrate transfer learning capabilities in a machine-learned algorithm trained for particle-flow reconstruction in high energy particle colliders. This paper presents a cross-detector fine-tuning study, where we initially pretrain the model on a large full simulation dataset from one detector design, and subsequently fine-tune the model on a sample with a different collider and detector design

We compute the renormalized charge current for a massless, minimally coupled, charged quantum scalar field on a charged Reissner-Nordström black hole space-time, using the method of pragmatic mode-sum renormalization. Since the field exhibits superradiance, we consider the past Unruh, Boulware and Candelas-Chrzanowski-Howard states and study how the renormalized current in these states depends on the

We present updated results for the wave function normalization constants and the first moments of the light-cone distribution amplitudes for the lowest-lying baryon octet. The analysis is carried out on a large number of nf=2+1 lattice gauge ensembles, including ensembles at physical pion (and kaon) masses. These are spread across five different lattice spacings, enabling a controlled continuum limit

Ultralight dark photon dark matter features distinctive cosmological and astrophysical signatures and is also supported by a burgeoning direct-detection program searching for its kinetic mixing with the ordinary photon over a wide mass range. Dark photons, however, cannot necessarily constitute the dark matter in all of this parameter space. In minimal models where the dark photon mass arises from

Nontrivial conformal field theories are rare. Motivated by the recent construction of a local higher-spin gravity in AdS4—chiral higher-spin gravity—we begin to identify its anti–de Sitter/conformal field theory (AdS/CFT) dual theory that has to be a closed subsector of Chern-Simons matter theories, thereby shedding more light on this class of CFTs and the dualities that relate them. We show that at

We argue that the Ising model conformal field theory (CFT) can be used to obtain some clear insights into three-dimensional (3D) (quantum) gravity with matter. We review arguments for the existence of its holographic description, and concentrate on the time dependence of perturbations of the theory at high temperature, which would correspond to throwing matter into a black hole in the dual picture

Isospin asymmetric nuclear matter is introduced to V-QCD, a bottom-up holographic QCD model. Using a small isospin chemical potential, we extract the symmetry energy in the model, finding excellent agreement with experimental results for some of the potentials. Extending the calculation for finite- and arbitrary-sized isospin chemical potentials, we construct β-equilibrated neutron stars via the usual

Prompted by several potential tetraquark states that have been reported by the LHCb, CMS, and ATLAS Collaborations in the di-J/Ψ and J/ΨΨ(2S) spectra, we investigate their contribution to two-photon processes. Within a nonrelativistic potential model for the all-charm tetraquark states, we calculate the two-photon decay widths of these states and test model-independent sum rule predictions. Imposing

We study the nonleptonic puzzle of Bd(s)→K(*)K¯(*) decay in the R-parity violating minimal supersymmetric standard model extended with the inverse seesaw mechanism. In this model, the chiral flip of sneutrinos can contribute to the observables LKK¯ and LK*K¯*, that is beneficial for explaining the relevant puzzle. We also find that this unique effect can engage in the Bs−B¯s mixing. We utilize the

In this short paper we want to generalize some recent concepts related to stubs in open string field theory. First, we modify the auxiliary field method by Erbin and Firat [Open string stub as an auxiliary string field, 2023.] to sliver frame stubs which are not even with respect to the Belavin-Polyakov-Zamolodchikov (BPZ) product. We then also show that the construction is consistent at the full quantum

Within the framework of nonrelativistic-QCD factorization, we perform a comprehensive investigation of the color singlet (CS) contribution to prompt J/ψ pair production at the CERN Large Hadron Collider at next-to-leading order (NLO) in αs. Specifically, we compare our NLO predictions with measurements from the LHCb, CMS, and ATLAS collaborations. We find that the CS contribution itself can well describe

In this paper we consider a massive self-interacting scalar quantum field in a Lorentz-violation scenario based on a Hořava-Lifshitz model. Specifically, we investigate the vacuum energy density and its loop correction, up to first order in the self-interaction coupling constant, and also the topological mass generation. These quantities are also analyzed in the case where the field is massless. The

We identify symmetries in a broad class of vectorlike confining dark sectors that forbid the leading electromagnetic moments that would ordinarily mediate dark baryon scattering with the Standard Model. The absence of these operators implies dark baryon dark matter has much smaller cross sections for elastic scattering off nuclei, leading to suppressed direct detection signals. In the confined description

In this work, we investigated the off-shell expansion relation of the Yang-Mills scalar theory. We explicitly showed that the single-trace Berends-Giele currents in the Yang-Mills scalar theory can be decomposed into a term expressed by a linear combination of bi-adjoint scalar Berends-Giele currents and one that vanishes under the on-shell limit. We proved that the bi-adjoint scalar currents, as well

If the dark sector possesses long-range self-interactions, these interactions can source dramatic collective instabilities even in astrophysical settings where the collisional mean free path is long. Here, we focus on the specific case of dark matter halos composed of a dark U(1) gauge sector undergoing a dissociative cluster merger. We study this by performing the first dedicated particle-in-cell

We investigate potential hadronic molecular states in the D(*)D¯(*) and B(*)B¯* systems using light meson exchange interactions. Our analysis focuses on coupled-channel systems with spin-parity quantum numbers JPC=0++, 1+±, and 2++, examining how the δ(r) potential affects states near threshold. Using coupled-channel analysis, we reproduce the X(3872) mass with a given cutoff for the (I)JPC=(0)1++

We compute next-to-leading order QCD corrections to the 1/mb2 terms of the heavy quark expansion, for the contribution to inclusive nonleptonic bottom hadron decays, induced by the charged-current operators mediating the b→cc¯s transition. Their contributions to the lifetimes are Cabibbo favored and have large Wilson coefficients, but they have not been computed before, since the presence of two heavy

We study the low energy dynamics of a system of two coupled real scalar fields in 1+1 dimensions using the flow equation approach of the similarity renormalization group in a wavelet basis. This paper presents an extension of the work by Michlin [Multiresolution decomposition of quantum field theories using wavelet bases, .] at one resolution higher. We also present the analysis of a model of two scalar

We study the interaction of two massive particles with a quantized gravitational field in its vacuum state using two different position observables: (i) a frame-dependent coordinate separation and (ii) a frame-independent geodesic separation. For free particles, (i) leads to purely unitary dynamics but (ii) leads to dissipation. For two particles coupled through a linear spring, (i) and (ii) lead to

We systematically explore the S-wave D1D1, D1D2* and D2*D2* states with various isospin-spin-orbit (ISL) configurations in the quark model. We propose nine stable dimeson states with the ISL configurations, ISL=001, 010, 012, 100, 102, 110, 112, 120, and 122, against dissociation into their constituent mesons. Those bound states are hydrogenlike molecular states, where the two subclusters are moderately

We investigate the thermal phase structure of the Berenstein-Maldacena-Nastase matrix model using nonperturbative lattice Monte Carlo calculations. Our main analyses span 3 orders of magnitude in the coupling, involving systems with sizes up to Nτ=24 lattice sites and SU(N) gauge groups with 8≤N≤16. In addition, we carry out extended checks of discretization artifacts for Nτ≤128 and gauge group SU(4)

We analyze the proton-box contribution to the hadronic light-by-light part of the muon’s anomalous magnetic moment, which is the first reported baryonic contribution to this piece. We follow the quark-loop analysis, incorporating the relevant data-driven and lattice proton form factors. Although the heavy mass expansion would yield a contribution of O(10−10), the damping of the form factors in the

We analyze the dynamics of Bogomol’nyi-Prasad-Sommerfield three-vortex solutions. First, for unexcited vortices, we study the two-dimensional moduli space of centered vortices with y→−y symmetry, and its metric. We identify the one-dimensional subspaces describing the head-on collisions of equidistant collinear and equilateral triangle configurations, where geodesic motion results in 90° and 60° scattering

We revisit optimization of functional renormalization group flows by analyzing regularized loop integrals. This leads us to a principle, the , and a corresponding order relation which allows us to order existing regularization schemes with respect to the stability of renormalization group flows. Moreover, the order relation can be used to construct new regulators in a systematic fashion. For studies

We present a new method for embedding a causal set into Minkowski spacetime. The method is similar to a previously presented method, but is simpler and provides better embedding results. The method uses spacetime volumes to define causal set analogs of time coordinates for all elements, and spatial distances for pairs of causally related elements. The spatial distances for causally related pairs are

Recently, the BESIII Collaboration updated the data for the exotic state, Ds0*(2317), with a mass of 2318.3±1.2±1.2 MeV from the positronium annihilation process. Inspired by the experiment, we systematically investigated the cq¯ meson family spectrum from the perspectives of two-quark, four-quark, and mixed two-four-quark structures, including Ds, Ds*, Ds0*(2317), and Ds1(2460), with the help of the

We analyze B0→K0ℓ¯ℓ long-distance contributions induced by the rescattering of a pair of charmed and charmed-strange mesons. We present an explicit estimate of these contributions using an effective description in terms of hadronic degrees of freedom, supplemented by data on the B0→D*Ds(Ds*D) transition in order to reproduce the corresponding discontinuity in the B0→K0ℓ¯ℓ amplitude. The D*Ds(Ds*D)K

Recent studies suggest that global fits of parton distribution functions (PDFs) might inadvertently “fit away” signs of new physics in the high-energy tails of the distributions measured at the high luminosity program of the LHC (HL-LHC). This could lead to spurious effects that might conceal key beyond the Standard Model (BSM) signatures and hinder the success of indirect searches for new physics

We investigate the discovery prospects for a vectorlike top partner (VLT) in the type-II two-Higgs-doublet model (2HDM-II) extended by a vectorlike quark doublet (TB) at the 14 TeV LHC. The study focuses on the pair production process pp→TT¯→bH+b¯H−→b(tb)b¯(t¯b), yielding fully hadronic final states characterized by high b-jet multiplicity. Two analysis strategies are employed, requiring at least four

We extract the complex frequency of the lowest quasinormal mode (QNM) from the holographically computed entropy density near thermodynamic equilibrium. The system under study is a purely thermal supersymmetric Yang-Mills N=4 plasma undergoing homogeneous isotropization dynamics. Starting from a far-from-equilibrium initial state, the system evolves toward equilibrium entropy, forming a stairway pattern

Based on an analysis that considers the isotropic CPT-odd standard model extension (SME) coefficients, we find new constraints for them coming from a combined DUNE and ESSnuSB fit. Furthermore, we investigate the correlations of the standard oscillation parameters, the leptonic CP-violating phase, δCP, and the atmospheric mixing angle, sin2θ23, with respect to the SME coefficients (aL)T. The combination

Heavy axions that couple to both quantum electrodynamics and quantum chromodynamics with masses on the order of MeV–GeV and high-scale decay constants in excess of ∼108GeV may arise generically in, e.g., axiverse constructions. In this work we provide the most sensitive search to date for the existence of such heavy axions using Fermi-LAT data toward four recent supernovae (SN): Cassiopea A, SN1987A

We study the patterns of multipartite entanglement in Chern-Simons theory with compact simple gauge group G and level k for states defined by the path integral on “link complements,” i.e., compact manifolds whose boundaries consist of n topologically linked tori. We focus on link complements which can be described topologically as fibrations over a Seifert surface. We show that the entanglement structure

Anti–de Sitter/QCD models are being extensively studied because they seem to offer an entirely tractable and radically different approach to the phases of QCD whose region of validity is precisely the region of strong interactions. In this context, a missing ingredient has been the absence of a bulk description dual to a hadronic phase at finite baryon density. In this work, we discuss a class of backgrounds

We introduce the parton shower for simulating quantum chromodynamics (QCD) radiation at hadron colliders and present numerical results from an implementation in the event generator . provides a consistent framework to quantify certain systematic uncertainties which cannot be eliminated by comparing the parton shower with analytic resummation. In particular, it allows us to study recoil effects away

The study of chaos and complexity in non-Hermitian quantum systems poses significant challenges due to the emergence of complex eigenvalues in their spectra. Recently, the singular value decomposition (SVD) method was proposed to address these challenges. In this work, we identify two critical shortcomings of the SVD approach when analyzing Krylov complexity and spectral statistics in non-Hermitian

We establish the general conditions under which evolution in the laws of physics leads to violations of the conservation of the energy-momentum tensor for matter, resulting in matter creation or destruction. They make use of global time variables canonically dual to the constants of nature. Such times flow at a rate determined by what can be interpret as the chemical potential of the fundamental constants

Quantum electrodynamics in 1+1D (QED2) shares intriguing properties with quantum chromodynamics (QCD), including confinement, string breaking, and interesting phase diagram when the nontrivial topological θ-term is considered. Its lattice regularization is a commonly used toy model for quantum simulations of gauge theories on near-term quantum devices. In this work, we address algorithms for adiabatic

We investigate two salient chaotic features, namely Lyapunov exponent and butterfly velocity, for an asymptotically Lifshitz black hole background with arbitrary dynamical critical exponent. These features are computed using three methods: entanglement wedge method, out-of-time-ordered correlator computation, and pole skipping. We present a comparative study where all of these methods yield exactly

Spectral densities connect correlation functions computed in quantum field theory to observables measured in experiments. For strongly interacting theories, their nonperturbative determinations from lattice simulations are therefore of primary importance. They entail the inverse Laplace transform of correlation functions calculated in Euclidean time. By making use of the Mellin transform, we derive

Marino’s Conjecture remains underexplored within the framework of SO(N) string dualities. In this article, we investigated the reformulated invariants of one-parameter families of knots [K]p derived from tangle surgery on Manolescu’s quasialternating knot diagrams [C. Manolescu, ]. Within topological string dualities, we have verified Marino’s integrality conjecture for these families of knots up to

The neutrino research program in the coming decades will require improved precision. A major source of uncertainty is the interaction of neutrinos with nuclei that serve as targets for such experiments. Broadly speaking, this interaction often depends, e.g., for charge-current quasielastic scattering, on the combination of “nucleon physics,” expressed by form factors, and “nuclear physics,” expressed

Dark matter could be a baryonic composite of stronglyc upled constituents transforming under SU(2)L. We classify the SU(2)L representations of baryons in a class of simple confining dark sectors and find that the lightest state can be a pure singlet or a singlet that mixes with other neutral components of SU(2)L representations, which strongly suppresses the dark matter candidate’s interactions with
