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 investigates the process in Pb-Pb ultraperipheral collisions and at lepton colliders by presenting NLO electroweak cross-section predictions and demonstrating the existence of genuine quantum entanglement in the system near the invariant mass threshold.
This paper leverages recent advances in Big Bang Nucleosynthesis theory and observational data, combined with principal component analysis, to establish model-independent constraints on early dark energy and investigate whether modifications to the expansion rate can resolve the lithium problem.
This paper presents the first estimate of the gamma-ray and X-ray flux induced by cosmic-ray scatterings on relic neutrinos, using Fermi-LAT data to establish stringent limits on cosmic neutrino background overdensity that significantly surpass current laboratory probes and rival IceCube constraints.
This paper proposes a minimal framework where asymmetric sterile neutrino dark matter is generated via the out-of-equilibrium decay of a scalar mediator in an asymmetric freeze-in mechanism, successfully reproducing the observed relic abundance while satisfying cosmological constraints through a non-thermal momentum distribution.
This paper demonstrates that a semi-decoupled dark sector with a higher temperature than the Standard Model plasma can significantly enhance the gravitational wave signal from the electroweak phase transition, potentially bringing it within the detectable range of future space-based interferometers without requiring extreme model parameters.
This paper presents a theoretical modeling of axion-like particle production and decay into photons in proton-proton and lead-lead collisions at 5.02 TeV and 13 TeV, utilizing Good-Walker eigenstate models to calculate cross-section dependencies on collision energy, ALP mass, and event numbers based on ATLAS light-by-light scattering data.
Using an improved Multi-Phase Transport model, this study demonstrates that the nuclear geometry and potential alpha clustering in O significantly influence anisotropic flows in O+O collisions at GeV, with the model successfully reproducing STAR data and establishing a baseline for future nuclear-structure investigations.
This paper presents a new local electron density map derived from parallax measurements of nearby pulsars, which suggests that many previously distant neutron stars are actually much closer and thus ideal candidates for future parallax campaigns to test fundamental physics, including dark matter heating mechanisms.
This paper derives and interprets the spatial density distributions of the axial-vector charge density for spin-1/2 systems using sharply localized wave packets in arbitrary Lorentz frames, while also examining the static approximation and its relation to Breit-frame distributions.
FeynGame 3.0 is a major software update that introduces QGRAF integration for visualizing Feynman graphs and implements various new features to facilitate the creation of publication-quality diagrams.
