The Simulating eXtreme Spacetimes Collaboration’s code SpEC can now routinely simulate binary black hole mergers undergoing orbits, with the longest simulations undergoing nearly orbits. While this sounds impressive, the mismatch between the highest resolutions for this long simulation is . Meanwhile, the mismatch between resolutions for the more typical simulations tends to be , despite the resolutions

The Laser Interferometer Space Antenna (LISA) will be a space-borne gravitational wave (GW) detector to be launched in the next decade. Central to LISA data analysis is time-delay interferometry (TDI), a numerical procedure which drastically reduces otherwise overwhelming laser frequency noise. LISA data analysis is usually performed on sets of TDI variables, e.g. Michelson variables or quasiorthogonal

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

There are several physical processes that mediate the interaction between an exoplanet and its host star, with the four main ones being due to magnetic, particle (stellar outflow), radiative, and tidal interactions. These interactions can be observed at different wavelengths, from X-ray to radio. Their strengths depend on the architecture of planetary systems, as well as the age and activity level

Chalcogenides (sulfides, selenides, tellurides, arsenides, antimonides) are important in natural processes, including formation of ore deposits on Earth, early stages of planetary accretion, and formation of condensates in planetary atmospheres. Their physicochemical properties render them suitable for a wide range of industrial applications. While thermodynamic data are available for many endmembers

More than 70% of Earth's magmatic output occurs in the ocean. This volcanism shapes major features of the seafloor, directly impacts the chemical composition of the oceans through water/rock interactions, and drives hydrothermal circulation of seawater. The formation of seafloor mineral deposits and chemosynthetic habitats that encircle the globe along mid-ocean ridges, volcanic arcs, and hotspots

The continental fossil record has exceptional, long sequences of fossiliferous strata that are the basis for evaluating ecosystem dynamics and their formative influences. The Siwalik sequence of South Asia is one example. It occurs in the Potwar Plateau (Punjab Province, Pakistan) and spans 18–1 Ma. The sequence consists of alluvial sediments deposited in a foreland basin created by the collision of

Emplacement of the Siberian Traps large igneous province (LIP) around 252 Ma coincided with the most profound environmental disruption of the past 500 million years. The enormous volume of the Siberian Traps, its ability to generate greenhouse gases and other volatiles, and a temporal coincidence with extinction all suggest a causal link. Patterns of marine and terrestrial extinction/recovery are consistent

The response of geologic matter when subjected to large-scale impact or explosion is dependent on the time history of the encompassing shock wave. The kinetics of localized physical and chemical transitions brought about by the shock wave are responsive to this time history. Solid-state viscosity of the media is responsible for establishing the time history of a shock wave. In 2003, researcher H. Jay

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

Heterodyne detection using microwave cavities is a promising method for detecting high-frequency gravitational waves (GWs) or ultralight axion dark matter. In this work, we report on studies conducted on a spherical 2-cell cavity developed by the MAGO collaboration for high-frequency GWs detection. Although fabricated around 20 years ago, the cavity had not been used since. Due to deviations from the

In this review, we show how combining dynamical and stellar population models with integral field spectroscopic data of nearby galaxies enable uncovering their assembly history. ▪ We discuss the advantages and limitations of various dynamical modelling approaches, focusing on measuring the mass distributions of nearby galaxies, including central black holes and dark matter halos. ▪ We highlight the

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

This work revises the Brane World Theory known as Randall Sundrum with the modification of an exponential, redshift-dependent brane tension. This model is studied in a scenario assuming no dark energy, with the aim of determining whether it can reproduce the Universe’s acceleration on its own, without the addition of a dark energy fluid. Bayesian Statistical analysis is performed in order to constrain

We study the entanglement dynamics of accelerated atoms using the theory of open quantum systems. We consider two atoms traveling along different hyperbolic trajectories with different proper times. We use the generalized master equation to discuss the dynamics of a pair of dipoles interacting with the electromagnetic field. The fundamental role played by proper acceleration in the entanglement harvesting

Gas giant planets, if present, are the most massive objects in a planetary system and play a pivotal role in shaping its overall architecture. The formation of these planets has constantly been a central issue in planetary science. Increasing evidence from spacecraft explorations of Jupiter and Saturn, as well as telescope observations of exoplanets, has provided new constraints on the formation process

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
