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 employs the Bronnikov-Konoplya-Pappas parametrization to analyze electromagnetic perturbations and quasinormal modes in both isolated and galactic Damour-Solodukhin wormholes, deriving observationally viable metrics constrained by Sgr A* shadow data and revealing that while oscillation frequencies remain stable, damping rates are highly sensitive to galactic compactness.
This paper presents a scalable quantum simulation framework for the real-time dynamics of the multi-flavor Gross-Neveu model on utility-scale superconducting processors, utilizing a hardware-efficient Trotterization and a novel Localized Diagonal Operator Approximation (LDOA) to successfully simulate systems beyond 100 qubits with results that align closely with exact diagonalization and tensor network benchmarks.
This study uses RHIC data to constrain in-medium mass modifications of protons and antiprotons and predicts that the detectability of their opposing correlations is highly sensitive to the temporal distribution of the source and is strongly enhanced in events with a larger ratio of antiproton to proton yield.
This paper reviews the current status and theoretical understanding of charmonium production in low-energy nuclear collisions at SPS, Fermilab, and HERA facilities, while outlining future prospects for measurements near the kinematic threshold in the upcoming CBM and NA60+ experiments.
This article demonstrates that the extended three-flavor quark-meson-diquark model, particularly through the inclusion of vector and axial-vector mesons, successfully describes massive hybrid stars with masses exceeding and radii consistent with astrophysical observations by generating a sufficiently stiff equation of state and a double-peak structure in the speed of sound, which is driven by the decreasing mass of the strange quark at high densities.
This paper demonstrates that the perturbative fragmentation function approximation for top-associated Higgs-boson production yields reliable results at LHC energies using a hybrid top-quark mass prescription, while the zero-mass prescription remains viable only for specific channels at LHC energies or for the full process at a 100 TeV collider, alongside a discussion of challenges in extending the formalism to NNLO.
This paper investigates the interaction and correlation functions of systems by modeling the as a molecular state within a fixed-center approximation framework, successfully reproducing experimental proton- data while predicting a structure near 1500–1600 MeV and a threshold cusp, but failing to support the existence of the , , or resonances.
This article proposes a low-reheating cosmological scenario in which light dark matter particles are produced via kaon decays and scatterings mediated by a flavor-changing operator, thereby establishing a testable connection between the dark matter relic abundance and the search for rare kaon decays in experiments such as NA62 and KOTO.
This overview summarizes novel theoretical and experimental advances, particularly data from the INDRA-FAZIA collaboration and calculations from the BUU transport model, to constrain the density dependence of the nuclear symmetry energy via isospin transport in heavy-ion collisions within the Fermi energy range.
This article presents the first investigation of the non-perturbative quark-gluon vertex in the complex plane within a symmetry-preserving framework, establishes a reliable analytic domain for its form factors in the soft-gluon limit, and outlines methods to extend this analysis to arbitrary momenta.
