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 how extending the Standard Model with multiple real singlets and varying symmetry structures can alleviate the stringent mass constraints on Dark Matter candidates found in single-singlet models, potentially opening up new detectable mass windows for future High-Luminosity LHC searches.
This paper presents an extensive analysis of the light CP-even Higgs boson pole mass in the MSSM and NMSSM using the newly implemented 3-loop FlexibleEFTHiggs hybrid calculation in FlexibleSUSY, focusing on its robustness in scenarios with highly non-degenerate SUSY spectra and providing an improved, uncertainty-assessed Higgs mass prediction for the NMSSM.
This paper investigates polarization-induced interference and gauge cancellations in high-energy multi-leg processes involving resonant weak bosons by introducing analytical decompositions of polarized propagators and a BRST-guided grouping scheme to refine predictions beyond the narrow-width approximation across various case studies.
By applying Wilson's naturalness criterion to address the limitations of standard fine-tuning definitions, this paper demonstrates that single-field inflationary models generating primordial black holes are not technically unnatural, contrary to common criticism.
This paper demonstrates that by employing a collision kernel conserving energy-momentum and particle current, the poles of the relativistic kinetic equation yield a dispersion relation with a systematic gradient structure where spatial and temporal gradients appear in unison, thereby ensuring causality in truncated hydrodynamic theories.
This paper presents a comprehensive finite-volume calculation of pion-pion scattering within Chiral Perturbation Theory and the Inverse Amplitude Method that incorporates discretization effects across all scattering channels and group representations, revealing significant corrections for small volumes () that improve the accuracy of energy level and phase-shift determinations compared to previous analyses.
This paper proposes a universal seesaw Pati-Salam model with a simple Higgs sector that unifies quarks and leptons into common multiplets, spontaneously breaks parity to solve the strong CP problem without an axion, and generates small Majorana neutrino masses through one-loop diagrams while remaining consistent with observed fermion masses.
The paper discusses the dominance of the imaginary part of the elastic scattering amplitude and advocates for an approximation method based on this dominance.
This paper investigates constraints on scalar Loryons within a Two Higgs Doublet Model, finding that while neutral singlet Loryons up to 700 GeV remain viable, those containing charged scalars are severely restricted by LHC data, unitarity, and Higgs decay observables.
This paper proposes a minimal generalized Proca model that successfully realizes a phantom-divide crossing at low redshifts while maintaining stability across all dynamical sectors and producing cosmological perturbation signatures consistent with current observational data.
