Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

This paper presents a unified framework within the NuWro Monte Carlo generator that consistently treats final-state interactions in quasielastic lepton-nucleus scattering by combining convolution-based inclusive calculations with an event-level cascade classification, significantly improving agreement with both inclusive electron-scattering data and exclusive MicroBooNE measurements.
Using a soft-wall holographic QCD model with an AdS-RN metric, this study reveals that combined rotation and finite chemical potential induce spatially inhomogeneous chiral condensation and additively suppress the chiral phase transition temperature, creating a position-dependent phase structure relevant to non-central heavy-ion collisions.
This paper characterizes the entanglement dynamics of helicity degrees of freedom in QED scattering processes by modeling them as quantum maps derived from discrete symmetries, demonstrating that maximal entanglement is preserved for fermion-only interactions and that iterative application of these maps typically drives arbitrary initial states toward asymptotic maximally entangled fixed points.
This paper proposes an analytic formalism for a non-minimally coupled inflationary model involving derivative interactions between gravity and a scalar field, demonstrating that it successfully generates scalar spectral index and tensor-to-scalar ratio values consistent with ACT and Planck observations across a wide range of inflaton potentials without encountering singularities in the slow-roll regime.
This paper presents a brief biography of William A. Bardeen (1941–2025), an American theoretical physicist at Fermilab renowned for his foundational contributions to the chiral anomaly, quantum chromodynamics, dynamical electroweak symmetry breaking, and heavy-light quark bound states.
The paper proposes DREAMuS, a fixed-target experiment at HIAF designed to search for GeV-scale muon-philic dark matter mediated by light flavor-violating bosons, demonstrating competitive sensitivity to couplings around and highlighting the enhanced discovery potential of a complementary beam option for sub-200 MeV dark matter.
This paper compares the pion decay width in a uniform magnetic field calculated via chiral perturbation theory with lattice QCD results, finding consistency at large magnetic fields while attributing discrepancies at weak fields to differences in pion decay constants.
This paper introduces and validates a novel no-reaction-plane method for extracting directed and elliptic flows in heavy-ion collisions using simple count asymmetries, demonstrating through PHSD model simulations that it accurately captures flow fluctuations without the need for event-plane reconstruction.
This paper utilizes QCD sum rule methods to model the resonance as a all-charm tetraquark in a diquark-antidiquark configuration, calculating its mass and decay widths to demonstrate consistency with experimental data and support its interpretation as a tensor state.
This paper investigates the lifetimes and inclusive semileptonic decay widths of doubly heavy baryons using the heavy quark expansion with next-to-leading-order corrections and bag model matrix elements, predicting specific lifetime hierarchies and highlighting the crucial role of -exchange contributions in explaining the large lifetime splitting observed in the doubly charmed sector.
