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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes that a high-quality axion protected by a discrete gauge symmetry can naturally resolve the isocurvature problem in high-scale inflation by inducing a large effective axion mass during inflation, thereby simultaneously addressing the axion quality problem and predicting testable parameter spaces for future experiments.
This study employs Bayesian inference to incorporate longitudinal spin polarization of hyperons alongside conventional bulk observables in Pb+Pb collisions at 5.02 TeV, demonstrating that while current uncertainties prevent a statistically significant shift in the extracted bulk viscosity, spin polarization serves as a valuable complementary probe for constraining quark-gluon plasma transport properties.
This study applies the Remler formalism within the Parton-Hadron-String Dynamics (PHSD) framework to investigate charmonium production and dissociation in baryon-rich matter at SPS and FAIR energies, demonstrating that an in-medium heavy quark potential successfully describes experimental data at SPS while providing estimates for future GSI/FAIR collisions.
This paper investigates the one-loop Polyakov-loop effective potential in accelerated gluonic matter using both Euclidean Rindler and optical spacetime formulations to resolve thermodynamic discrepancies, ultimately demonstrating that real acceleration enhances deconfinement while imaginary acceleration suggests a confined phase.
This paper establishes a practical framework for constructing thermodynamically consistent observables in the symmetry-improved Cornwall-Jackiw-Tomboulis formalism by proposing and comparing various pressure prescriptions within a three-flavor linear sigma model with quarks, demonstrating that while quantitative differences exist near phase transitions, the global thermodynamic structure remains stable.
This paper establishes that the occurrence of "magic relations" in Feynman integrals is intrinsically linked to the presence of higher-dimensional critical varieties, providing a practical computational test to detect these identities, count master integrals, and analyze their behavior under symmetries and cuts.
This paper presents a lattice QCD calculation of the charged-neutral pion mass splitting using a Pauli-Villars-regulated photon propagator to avoid power-law finite-volume effects, yielding a result of 4.56(22) MeV that agrees well with experimental measurements and validates the formalism for future electromagnetic corrections.
This paper presents lattice QCD results for the first four Mellin moments of the unpolarized parton distribution functions of the pion and kaon, computed using a physical-mass twisted mass fermion ensemble to reconstruct the valence PDFs and compare them with existing theoretical and phenomenological determinations.
This paper proposes that the low-energy excess observed in cryogenic calorimeters arises from surface dislocations nucleated by thermal contraction mismatches between the absorber and underlying SiO layers, offering a solid-state explanation and suggesting detector design modifications to test and mitigate this background.
This paper introduces HyperPrecision, a Mathematica package that enables high-precision numerical evaluation of multivariate hypergeometric functions and their Laurent expansions by automatically constructing Pfaffian systems, reducing them to ordinary differential equations along a contour, and solving them via the Frobenius method to overcome convergence limitations in physics and mathematics applications.
