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 study employs a Bayesian approach to generate hybrid star equations of state combining hadronic and quark matter models, demonstrating that vector and multiquark interactions are essential for supporting massive neutron stars consistent with NICER and pQCD constraints while predicting a positive trace anomaly in their cores.
This paper employs perturbative methods within de Sitter electroweak theory to calculate the production rates and resulting number density of bosons emitted from neutrino decays in the early Universe, analyzing their dependence on particle momenta and renormalization mass.
This paper provides practical recommendations and considerations from researchers across major particle physics experiments on adopting emerging machine learning-based unbinned unfolding techniques to replace traditional binned histogram methods for more flexible, high-dimensional data analysis.
This paper presents a next-to-leading order QCD calculation of diboson production with leptonic decays and definite polarization states within the SMEFT framework, matched to parton showers to enable precise polarization-template and quantum-tomography analyses at the LHC.
This paper demonstrates that gravitational instantons, specifically Eguchi-Hanson geometries, induce quantized fluxes that enforce global boundary conditions on fermion wavefunctions and, upon summation over flux sectors in the path integral, gauge the Standard Model's 1-form symmetry, thereby proving it cannot persist as an exact global symmetry while simultaneously inducing exponentially suppressed baryon- and lepton-number violating processes.
This paper investigates the conditions under which first-order phase transitions associated with spontaneous lepton number breaking in flat potential models can generate observable gravitational wave signatures, offering a mechanism to dilute late-time relics via thermal inflation without erasing the baryon asymmetry.
This paper investigates a scenario where light Higgsinos and right-handed sneutrinos contribute to dark matter via freeze-out and freeze-in mechanisms, respectively, but ultimately rules it out because the resulting over-abundant sterile neutrinos have lifetimes exceeding the age of the universe.
This study employs Bayesian inference with hadronic and quark matter models to demonstrate that while the presence of large quark cores in 1.4 solar mass neutron stars depends on the specific quark model used, both frameworks predict quark matter in 2 solar mass stars, with the mass-radius curve slope serving as a key indicator of non-nucleonic matter.
Using a lattice Boltzmann-Uehling-Uhlenbeck transport model with a density-, momentum-, and isospin-dependent NLO Skyrme pseudopotential, this study analyzes proton anisotropic flows in Au+Au collisions at to demonstrate their strong sensitivity to momentum-dependent mean-field potentials and the symmetric nuclear matter incompressibility, while highlighting the need to incorporate higher-order equation-of-state parameters and in-medium cross-section modifications for future Bayesian extractions of nuclear matter properties.
This paper presents the first implementation of a quantum vacuum signal emission module within an established diffractive beam propagation toolkit, enabling realistic modeling of optical experiments to accurately predict and separate vacuum birefringence signals from background noise in counter-propagating laser beam collisions.
