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 one-loop Ward-Takahashi identity for a spinless fermion bound state in the light-front formalism, demonstrating that its validity relies on the crucial contributions of pair production diagrams and the necessary inclusion of zero modes.
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.
MadSpace is a modular C++ library with native GPU support that unifies phase-space construction, adaptive and neural importance sampling, and event unweighting within a compute-graph framework, offering a high-level Python interface for seamless integration with machine learning workflows.
This paper evaluates strategies for selecting or fitting Parton Distribution Functions (PDFs) to ensure robust New Physics searches at the High-Luminosity LHC, comparing conservative approaches that exclude potentially contaminated high-energy data against simultaneous fits of PDFs and Standard Model Effective Field Theory (SMEFT) coefficients, with applications to Drell-Yan and top-quark pair production.
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 introduces a systematic approach called GOOFy, utilizing non-consistent generalized charge conjugation transformations to construct new field-theoretical models where parameter relations remain stable under renormalization group evolution, a framework that excludes the Standard Model but supports the two-Higgs-Doublet Model as a viable extension.
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.
