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 exclusive semileptonic decays of using a light-front quark model that incorporates nonvalence contributions, yielding branching ratios consistent with recent BESIII measurements and demonstrating the significant role of these nonvalence effects in such baryon decays.
This paper utilizes the superfield formalism to demonstrate that color confinement in QCD arises from BRST-bound states that render gluons and quarks massive dipole fields, a mechanism the authors propose could similarly resolve the unitarity violation caused by massive ghosts in quadratic gravity.
This paper demonstrates that in a GUT-inspired gauge-Higgs unification model on a Randall-Sundrum warped space, the total gauge anomalies, despite flowing with the Aharonov-Bohm phase, become universal and independent of bulk mass parameters, ensuring anomaly cancellation within each generation even when the phase is non-zero.
This paper presents a validated implementation of the ATLAS triple Higgs to six -jets search in CheckMATE and Rivet, utilizing it to establish exclusion limits for Standard Model and TRSM benchmarks and to project High Luminosity LHC sensitivity under various systematic uncertainty scenarios.
This paper proposes a novel counter reflection symmetry for the neutrino mass matrix, which naturally accommodates an inverted mass hierarchy and can be realized within a minimal framework based on symmetry.
COSMOS is a standalone, OpenMP-parallelized C++ numerical relativity code designed to simulate primordial black hole formation by solving the Einstein equations in 3+1 dimensions using specialized non-Cartesian scale-up coordinates and fixed mesh refinement to handle non-linear gravitational dynamics.
This paper demonstrates that the -term extended NMSSM can simultaneously accommodate persistent scalar excesses at LEP and the LHC while satisfying stringent heavy scalar cascade constraints, offering viable parameter regions with distinct coupling patterns and predicting specific long-lived neutralino signatures for positive- scenarios.
This paper calculates the azimuthal angular decorrelation of diffractive dijets in ultra-peripheral heavy-ion, $ep$, and collisions using all-order resummation of soft gluon emissions to demonstrate that this observable serves as a promising probe for non-perturbative diffractive transverse momentum-dependent distributions, with numerical predictions provided for LHC, HERA, and the future EIC.
This paper extends the standard Fickian diffusion model to Maxwell–Cattaneo diffusion to account for finite current-relaxation time, deriving closed evolution equations that reveal how this memory effect suppresses, shifts, and reshapes the non-monotonic behavior of conserved charge cumulants in the quark-gluon plasma.
This comment refutes the claim that Electroweak Penguin-tree relations (ETRs) are invalid by demonstrating their mathematical rigor as exact group-theoretical results under unbroken SU(3) symmetry, thereby explaining the discrepancy with a recent fit that yielded poor results when ETRs were applied.
