The proton–proton collisions at the Large Hadron Collider (LHC) produce an intense, high-energy beam of neutrinos of all flavors collimated in the forward direction. Recently, two dedicated neutrino experiments, FASER (Forward Search Experiment) and SND@LHC (Scattering and Neutrino Detector at the LHC), have started operating to take advantage of the TeV-energy LHC neutrino beam. First results were

In this work, we address the localization problem of vector field in the chameleon braneworld and investigate the localization of various matter fields. The conditions for localizing the matter fields are determined. It is found that the zero modes of scalar, vector, and fermion fields can be successfully localized, yet the zero mode of the Kalb-Ramond field cannot be localized, which implies the recovery

In this paper, we explore the properties of the Ellis-Jaffe Sum Rule (EJSR) by employing the Principle of Maximum Conformality (PMC) approach to address its perturbative part up to next-to-next-to-next-to-leading order (N3LO) QCD contributions. By applying the PMC, we achieve a precise perturbative QCD prediction for the EJSR, free from conventional ambiguities associated with the renormalization scale

In this work, we perform a statistical inference of the classical background law governing the evolution of the temperature of the cosmic microwave background radiation (CMB), given by TCMB(z)=T0(1+z). To this end, we employ Gaussian Process (GP) regression techniques to reconstruct the temperature evolution based on two observational datasets: (i) CMB–Sunyaev-Zel'dovich (SZ) cluster measurements and

Shell evolution has been systematically investigated in neutron-rich isotopes, revealing many exotic properties such as the disappearance of traditional magic numbers and the emergence of new ones. However, research on proton-rich nuclei remains limited. In this study, we utilize ab initio valence-space in-medium similarity renormalization group approach using chiral effective field theory-derived

One of the characteristics of a dynamical black hole is the apparent horizon. Initially it was assumed that this surface is spacelike. However, further studies have shown that it can be both and null and timelike. Recent studies of the black hole shadow have demonstrated the connection between energy conditions and the black hole shadow [6]. In this paper, we establish a connection between the behavior

A combined constraint on the QCD equation of state, at high densities, from connecting neutron star observations to data from heavy ion reactions is presented. We use the Chiral Mean Field Model which can describe neutron star and iso-spin symmetric matter and allows the consistent calculation of the density and momentum dependent potentials of baryons which are then implemented in the UrQMD transport

The Bargmann-Michel-Telegdi equation, which describes the precession of the spin of a charged Dirac particle moving in a homogeneous electromagnetic field, is generalized to include also other homogeneous background fields. The treatment incorporates observable coefficients that govern operators of mass dimensions three through six in the underlying Dirac effective field theory. A relativistic formulation

In this work, we study the effect of gluon condensate on the DC conductivity and butterfly effect using AdS/CFT. First, by considering the butterfly velocity defined by the metric, we find that the butterfly velocity decreases with the increase of gluon condensate parameter c. This indicates that gluon condensation increases the disorder or chaotic behavior within the system. Next, we expand the drag

The strong force which binds hadrons is described by the theory of quantum chromodynamics (QCD). Determining the character and manifestations of QCD is one of the most important and challenging outstanding issues necessary for a comprehensive understanding of the structure of hadrons. Within the context of the QCD parton picture, the parton distribution functions (PDFs) have been remarkably successful

We suggest a quantum circuit model which simulates the black-hole evaporation process. In particular, Almheiri-Marolf-Polchinski-Sully (AMPS) paradox and the ER=EPR correspondence are reconsidered regarding our proposed model, which assumes a Maxwell's demon operating within a black hole interior. In other words, we form a quantum circuit, mimicking the behavior of the entanglement structure of the

In this paper, we investigate the elastic scattering of an electron by a Yukawa potential within the framework of non-commutative (NC) geometry. We first derive the NC correction to the Yukawa potential at leading order in the NC parameter, resulting in a modified potential resembling a screened Kratzer potential. This potential reduces to the standard Kratzer form when considering the NC correction

Significant continuum strength has been observed to be populated in 17C produced in the d(16C,p) reaction at a beam energy of 17.2 MeV/nucleon. The strength appears at greater than ∼2 MeV above the single-neutron decay threshold and has been identified as arising from transfer into the neutron 0d3/2 orbital. Guided by shell model predictions the greater majority of the strength is associated with a

We solve the nucleon's wave functions from the eigenstates of the light-front quantum chromodynamics Hamiltonian for the first time, using a fully relativistic and nonperturbative approach based on light-front quantization, without an explicit confining potential. These eigenstates are determined for the three-quark, three-quark-gluon, and three-quark-quark-antiquark Fock representations, making them

Proton-neutron configurations in atomic nuclei can manifest in a variety of different structures, and exotic nuclei provide fruitful ground for exploring their relation to fundamental symmetries. Here, we report on in-beam γ-ray spectroscopy of the very neutron-deficient 184Pb nucleus using the jurogam II spectrometer at the ritu separator in a recoil-decay tagging experiment. For the first time, transitions

We investigate the geometry, dynamics, and collision mechanisms in the ergoregion of Kerr-Newman-AdS black hole influenced by quintessential energy. Particle splittings within the ergoregion are analyzed, demonstrating their role in energy extraction via the Penrose process. Increased spin elongates the ergosphere, while higher quintessential parameters expand static limits and distort photon regions

Considering environment-induced interatomic interaction, we study the entanglement dynamics of two uniformly accelerated atoms that interact with fluctuating massless scalar fields in the Minkowski vacuum in the presence of a reflecting boundary. The two atoms are initially prepared in a state such that one is in the ground state and the other is in the excited state, which is separable. When the acceleration

We study the effect of Spontaneous Lorentz Symmetry Breaking (SLSB) on Primordial Gravitational Waves (PGWs) generated during inflation. The SLSB is induced by a time-like Bumblebee vector field which is non-minimally coupled to the Ricci tensor in the Friedmann-Lemaître-Robertson-Walker background. The power spectrum and GW amplitude are computed to investigate how Lorentz violation leaves observable

In accordance with P. Vogel, a set of algebra structures in Chern-Simons theory can be made universal, independent of a particular family of simple Lie algebras. In particular, this means that various quantities in the adjoint representations of these simple Lie algebras such as dimensions and quantum dimensions, Racah coefficients, etc. are simple rational functions of two parameters on Vogel's plane

This study explores the thermodynamic properties of evolving Lorentzian wormholes within the framework of f(R,T) gravity. This modified gravity theory extends general relativity by incorporating the Ricci scalar (R) and the trace of the energy-momentum tensor (T). We investigate the thermodynamics of wormholes at their dynamic apparent horizon, deriving expressions for the entropy variation and testing

We start from the classical Kadomtsev-Petviashvili (KP) hierarchy posed on formal pseudo-differential operators, and we produce new hierarchies of non-linear equations in the context of non-formal pseudo-differential operators lying in the Kontsevich and Vishik's odd class. In particular, we show that it is possible to lift the standard KP hierarchy to hierarchies of differential equations for non-formal

We investigate the properties of nucleons at finite temperature and density using a two-flavor quark meson model with Gaussian fluctuations that extend beyond the mean-field approximation. Our findings suggest that Gaussian fluctuations lead to a non-monotonic behavior of the nucleon mass as a function of temperature and density, which may play an important role in the study of the hadronization process

It is widely observed that particles produced in high-energy collisions follow a power-law distribution. One such power-law distribution used extensively in the phenomenological studies owes its origin to nonadditive statistics proposed by C. Tsallis. In this article, we derive a novel nonadditive generalization of the conventional Bose-Einstein distribution using a single-mode harmonic oscillator

A precise quantification of the medium-modification of the high transverse momenta jets in relativistic heavy ion collisions rely on consistent modeling of elastic and inelastic energy loss suffered by the jet and the concurrent underlying medium evolution. We have developed a unified framework for jet and bulk medium evolution within a multiphase transport approach where the jets and medium share

Pole-skipping offers compelling evidence for the hydrodynamic origin of chaotic behavior in strongly coupled quantum systems. We demonstrate that the cumulative effect of higher-order corrections to the hydrodynamic diffusive mode, captured by the parameter Ω, determines the thermal diffusivity through chaos parameters, providing new insights into the interplay between chaos and hydrodynamics. In the

Quantum knot invariants (like colored HOMFLY-PT or Kauffman polynomials) are a distinguished class of non-perturbative topological invariants. Any known way to construct them (via Chern-Simons theory or quantum R-matrix) starts with a finite simple Lie algebra. Another set of knot invariants – of finite type – is related to quantum invariants via a perturbative expansion. However can all finite type

White dwarfs (WDs), as the remnants of low to intermediate-mass stars, provide a unique opportunity to explore the interplay between quantum mechanical degeneracy pressure and gravitational forces under extreme conditions. In this study, we examine the structure and macroscopic properties of WDs within the framework of 4D Einstein-Gauss-Bonnet (4DEGB) gravity, a modified theory that incorporates higher-order

This study presents the first measurement of the f1(1285) resonance using the ALICE detector in inelastic proton–proton collisions at a center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity (|y|< 0.5) through the hadronic decay channel f1(1285)→KS0K±π∓. Key measurements include the determination of its mass, transverse-momentum integrated yield, and average transverse momentum

The transverse charge density of the pion is extracted from a dispersive analysis of the e+e−→π+π− exclusive annihilation data. A logarithmic dispersion relation is used to compute the unknown phase of the timelike pion form factor from the modulus obtained from the annihilation cross section. The method is model-independent and permits quantitative uncertainty estimates. The density is obtained with

We discuss the phenomenology at hadron colliders of a pseudoscalar Higgs boson A, as predicted in many extensions of the Standard Model. In particular, we highlight the aspects that makes it different from the case of a quasi-bound toponium state. We apply the discussion to the excess of tt¯ threshold events recently observed at the LHC by the CMS collaboration [1], which could in principle be due

We calculate all leading-twist gluon generalized parton distributions (GPDs) inside the proton at nonzero skewness using the basis light-front quantization framework. The proton's light-front wave functions are derived from a light-front quantized Hamiltonian incorporating Quantum Chromodynamics inputs. Our study includes the valence Fock sector with three constituent quarks and an additional Fock

We consider the beam-charge asymmetry of the J/ψ production cross sections in π−- versus π+-induced reactions on proton or nuclear targets. We show that the J/ψ production cross section difference between π− and π+ beams impinging on a proton target has a positive sign with a magnitude proportional to the product of pion's valence quark distribution, Vπ, and proton's up and down valence quark distribution

In this article we construct the holonomy operator for spin connection in (1+3)-dimensional LQG based on the twisted geometry. The starting point of the construction is to express the holonomy of the spin connection on a graph in terms of the twisted geometry variables, and we check that this expression reproduces the spin connection in terms of triads in a certain continuum limit. By using the twisted

We examine black hole thermodynamics within the framework of modified Rényi entropy and explore its implications in Modified Newtonian Dynamics (MOND), an extension of Newton's second law proposed to explain galaxy rotation curves without invoking dark matter. We conjecture that Tsallis entropy provides an exact description of Bekenstein–Hawking entropy, from which the modified Rényi entropy is derived

We present a novel approach for investigating the spin structure of hadrons based on the two-point function in quantum field theory. In a rotating frame, we derive two independent expressions of the two-point function and identify their equivalence, which allows for a complete decomposition of the total spin of a composite system into the angular momenta of its constituent particles. Applying this

We measured the β-delayed neutron emission from 25F for the first time at the Facility for Rare Isotope Beams (FRIB). Using combined neutron and γ-ray detector systems of the FRIB Decay Station Initiator (FDSi), we observed β-decay transitions populating neutron unbound states between 4.2 and 8 MeV in 25Ne. The experimental results led to the revision of the β-decay half-life and β-delayed neutron-emission

Electron antineutrinos are emitted in the decay chains of the fission products inside a reactor core and could be used for remote monitoring of nuclear reactors. The DANSS detector is placed under the core of the 3.1 GW power reactor at the Kalinin Nuclear Power Plant (KNPP) and collects up to 5000 antineutrino events per day. DANSS measured changes of the reactor power by antineutrino counting rates

We study properties of the Maxwell electromagnetic invariant in the external region of spinning and charged horizonless stars. We analytically find that the most negative value of the Maxwell electromagnetic invariant is obtained on the equator of the star surface. We are interested in scalar fields non-minimally coupled to the Maxwell electromagnetic invariant. The negative enough Maxwell electromagnetic

A direct search for new heavy neutral Higgs bosons ▪ and ▪ in the ▪ channel is presented, targeting the process ▪ with ▪. For the first time, the channel with decays of the ▪ boson to muons or electrons in association with all-hadronic decays of the ▪ system is targeted. The analysis uses proton-proton collision data collected at the CERN LHC with the CMS experiment at s=13TeV, which correspond to

Energy-energy correlators are constructed by averaging the number of charged particle pairs within jets, weighted by the product of their transverse momenta, as a function of the angular separation of the particles within a pair. They are sensitive to a multitude of perturbative and nonperturbative quantum chromodynamics phenomena in high-energy particle collisions. Using lead-lead data recorded with

In interstellar media characterized by a nonrelativistic plasma of electrons and heavy ions, we study the effect of axion dark matter coupled to photons on the dynamics of an electric field. In particular, we assume the presence of a background magnetic field aligned in a specific direction. We show that there is an energy transfer from the oscillating axion field to photons and then to the plasma

In Refs. [1,2] we provided a complete dispersive evaluation of the hadronic light-by-light (HLbL) contribution to the anomalous magnetic moment of the muon. While the evaluation strategy was developed for the kinematic situation determined by the muon mass, a similar approach also applies to the HLbL corrections to the anomalous magnetic moments of the electron and τ lepton, shifting the sensitivity

In the context of future electroweak precision measurements at the Future Circular Lepton Collider (FCC-ee), we consider recent proposals aimed at finding signatures of physics beyond the Standard Model. In particular, we focus on recent novel suggestions for very precise direct measurements of αem(MZ2). It is shown that at a level of precision of order 10−5, the effects of a dark photon may be very

We develop a smoothly matched and singularity-free model for a two-layered compact star, comprising an MIT bag model type dense core surrounded by a shell of Bose-Einstein condensate. Using a biquadratic spatial metric as the coherent background, the temporal metric potential for each layer is obtained by solving the Einstein field equations. This approach provides a comprehensive understanding of

In this study, we investigate the relativistic dynamics of fermions in a (2+1)-dimensional sector of the Bonnor-Melvin magnetic (BMM) spacetime background, which features a homogeneous magnetic field aligned with the symmetry axis and a nonzero cosmological constant while maintaining Lorentz invariance under boosts along the z-direction. We analyze the (2+1)-dimensional solution in gravity coupled

In this Letter, we probe the quantum nature of the Kretschmann invariant K in the deep quantum regime that dominates in the vicinity of the black hole singularity. To overcome challenges in formulating a quantum mechanical operator Kˆ corresponding to the Kretschmann invariant, we employ Bohmian quantum interpretation for the Wheeler-DeWitt equation that emerges from a Kantowski-Sachs representation

We introduce novel black hole (BH) solutions, charge/non-charge, within the framework of f(R) gravity, a theory that does not inherently include a cosmological constant, using equal/different metric ansatzs. Remarkably, these solutions exhibit asymptotically Anti-de Sitter (AdS) or de Sitter (dS) behavior, depending on their parameter values. Unlike the BTZ solutions of General Relativity, which feature

Very recently the Wood-Saxon (WS) type interaction in the single-folding potential (SFP) approach are constructed to simulate the ϕ-α potentials. One set of the ϕ-α potentials are based on the first principle HAL QCD ϕ-N interactions in S3/24 channel, and in another set, the ϕ-meson nucleus potentials were calculated by employing the quark-meson coupling (QMC) model. By utilizing these two sets of

The discovery of solar neutrinos confirmed that the inner workings of the Sun generally match our theoretical understanding of the fusion process. Solar neutrinos have also played a role in discovering that neutrinos have mass and that they oscillate. We combine the latest solar neutrino data along with other oscillation data from reactors to determine the Sun's density profile. We derive constraints

We extend the Rioseco and Sarbach model into Reissner-Nordström black hole accretes degenerate relativistic Fermi gas. The accretion theory is based on the Boyer-Lindquist coordinates and the Fermi gas follows Fermi-Dirac statistics at infinity. The expressions for the particle current density, the stress energy-momentum tensor, and three accretion rates are derived. We first investigated the impact

We perform an analysis of the potential impact of future D- and B-meson measurement within the SMOG2 fixed-target program at the LHCb experiment on nuclear parton distribution functions. Following [1], we assume that SMOG2 will collect data for five nuclear targets: He, Ne, Ar, Kr, Xe and hydrogen which will provide a baseline for constructing nuclear ratios. The analysis is performed by using the

We study the production and possible detection of a single Higgs boson in association with a top quark in proton-proton collisions (pp→th+X) at the High-Luminosity Large Hadron Collider. This process absent in the Standard Model is predicted by other models such as the Two-Higgs Doublet Model of type III, which is the theoretical framework adopted in this work. Promising results are found for specific

We provide an update on QCD predictions for top-quark pair production close to threshold including bound state effects at the Large Hadron Collider. We compute the top-quark pair invariant mass distribution dσ/dMtt¯, including Coulomb resummation for bound-state effects, as well as threshold resummation for emissions of soft and collinear gluons. We discuss uncertainty estimates and present a proposal

We explore the confining pressure inside the nucleon and the related gravitational form factor referred to as the D-term, using the skyrmion approach based on the scale-invariant chiral perturbation theory, where the skyrmion is described as the nucleon and a scalar meson couples to the scale anomaly through the low energy theorem. Within this model framework, the current quark mass and gluonic quantum

We report on the first ab initio informed α knock-out reaction in the intermediate-mass region, with the aim to probe the underlying chiral potential and its impact on the emergence of alpha clustering in this mass region. The theoretical predictions of the α+16O clustering in the 20Ne ground state, based on the ab initio symmetry-adapted no-core shell model with continuum, yield a triple differential

In collider physics, the properties of hadronic jets are often measured as a function of their lab-frame momenta. However, jet fragmentation must occur in a particular rest frame defined by all color-connected particles. Since this frame may not be the lab frame, the fragmentation of a jet depends on the properties of its sibling objects. This non-factorizability of jets has consequences for experimental

The validation, verification, and uncertainty quantification of computationally expensive theoretical models of quantum many-body systems require the construction of fast and accurate emulators. In this work, we develop emulators for auxiliary field diffusion Monte Carlo (AFDMC), a powerful many-body method for nuclear systems. We introduce a reduced-basis method (RBM) emulator for AFDMC and study

We propose a novel leptogenesis scenario utilising the two-body decay of heavy right handed neutrino (RHN) via the electromagnetic dipole operator. While the requirement of the standard model (SM) gauge invariance requires such dipole operator only at dimension-6 forcing the generation of non-zero CP asymmetry from three-body decay with two-loop corrections, we write down dimension-5 dipole operators

We show that the use of realistic πK interactions, obtained from a dispersive analysis of scattering data, as well as relativistic corrections, are essential to describe recently observed π±KS femtoscopic correlations. We demonstrate that the spontaneous chiral symmetry breaking dynamics and the non-ordinary features of the κ/K0⁎(700) resonance, together with large cancellations between isospin channels
