This paper calculates the axial-vector form factor for pion decay () using pseudovector coupling with a non-perturbative term and a lowest-order constant self-energy approximation, demonstrating that the inclusion of a specific parameter significantly improves the calculated values for both the axial and vector form factors.
This paper establishes the general functional form of the Euclidean energy-momentum tensor two-point function at zero and finite temperatures by decomposing it into fundamental tensorial structures, deriving differential relations via energy-momentum conservation, and expressing the full correlator in terms of a reduced set of spectral functions to facilitate more efficient lattice investigations.
This paper discusses the theoretical signatures and main QCD backgrounds of instanton (sphaleron) production events, proposing experimental searches for these unobserved phenomena via diffractive events at the LHC and spin-spin correlations between hyperons at NICA.
This paper proposes a novel invariant-mass observable using the resonance to experimentally distinguish between nucleon coalescence and statistical thermal models for deuteron formation at the LHC, demonstrating that a specific resonance peak in the proxy mass spectrum emerges exclusively in the coalescence scenario.
This paper employs holographic duality within a Maxwell-Chern-Simons theory to derive all-order gradient constitutive relations for chiral plasma under strong magnetic fields, utilizing thirteen transport coefficients to analyze anomaly-induced phenomena like negative magnetoresistance and chiral magnetic waves beyond the hydrodynamic limit.
This study investigates the magnetic moments of octet baryons in isospin asymmetric strange matter under strong magnetic fields using a unified CQMF and CQM framework, revealing that finite-temperature Dirac sea effects induce magnetic catalysis and a monotonic increase in baryon effective masses, thereby highlighting the critical role of vacuum polarization in electromagnetic properties relevant to heavy-ion collisions and compact stars.
This paper utilizes exact calculations within Carroll-Field-Jackiw electrodynamics to demonstrate that Cherenkov radiation in anisotropic chiral matter can occur without a velocity threshold for slowly moving charges within specific frequency ranges, while also characterizing the resulting multi-cone emission patterns and validating the reliability of previous approximate methods.
This paper demonstrates that realistic microscopic wave functions for nuclear clusters and hypernuclei exhibit broader, non-Gaussian spatial distributions compared to Gaussian approximations, and proposes a mechanism using phenomenological two-body interactions to explain the underestimation of cluster yields in theoretical models.
This paper introduces Ph-CDM, a General Relativity model utilizing a phantom scalar with a wrong-sign kinetic term to drive a smooth late-time transition from anti-de Sitter to de Sitter space, thereby offering a controlled mechanism to resolve cosmological tensions without resulting in a Big Rip.
This paper presents a proof-of-concept implementation of the matrix element method at next-to-leading order (NLO) accuracy using the POWHEG framework, demonstrating its effectiveness as a near-optimal classifier for distinguishing Standard Model from beyond-the-Standard-Model events in fully leptonic production by leveraging spin- and polarization-dependent correlations.
