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 proposes a viable dark matter scenario within the inverse scotogenic model where nearly degenerate dark scalars achieve the correct relic abundance through coscattering and coannihilation processes, while simultaneously satisfying constraints from lepton flavor violation, direct detection, and cosmological observations, and predicting observable displaced vertex signatures from the decay of the heavier scalar.
This paper demonstrates that viewing two-body scattering as an SU(N)-equivariant map reveals how the representation-theoretic structure of the S-matrix dictates entanglement generation, showing that Yang-Mills theory uniquely maximizes color entanglement at right angles and that preserving maximal entanglement in helicity space enforces the theory's fundamental algebraic constraints.
This paper demonstrates that the widely used Gaussian Approximation fails to accurately describe incoherent diffraction in photon-nucleus collisions because it cannot capture the essential four-gluon exchange dynamics, leading to systematically underestimated cross sections compared to the full JIMWLK evolution across all kinematic regimes.
This paper proposes a novel, infrared-safe definition of the one-point charge correlator in the Breit frame for deep-inelastic scattering, utilizing soft-collinear effective theory to establish its connection to nucleon structure and transverse momentum-dependent distributions while deriving singular distributions up to and resumming logarithmic corrections to high precision.
This paper demonstrates that dark matter admixture in neutron stars can significantly reduce crust thickness and increase torsional oscillation frequencies, particularly when a "dark core" forms, offering a potential observational method to distinguish dark matter effects from microphysical uncertainties like electron screening.
This paper discusses two recent high-precision studies on radiative corrections in bound states: one resolving a long-standing discrepancy in muon decay rates for light nuclei (), and another calculating the boson contribution to parapositronium decay, which yields a rate many orders of magnitude smaller than previously estimated.
This paper presents a phenomenological study demonstrating that production at the LHC is sensitive to light spin-1 dark matter mediators and that CP-sensitive angular observables can effectively distinguish between vector, axial-vector, scalar, and pseudoscalar mediator hypotheses.
This article explores the physics challenges involved in bridging the quark parton model, which emerged from deeply inelastic scattering experiments, with its evolution into the full theory of quantum chromodynamics (QCD).
The paper introduces HydroGrav, a C++ code that utilizes exact equations of state derived from effective potentials to compute precise fluid profiles and gravitational wave spectra for cosmological phase transitions, demonstrating significant deviations from simplified models in a -symmetric extension of the Standard Model and quantifying their impact on LISA detectability.
This paper presents the first phenomenological study estimating the branching ratios and kinematic yields of antideuteron production from beauty-hadron decays, providing a crucial benchmark for future searches by the ALICE experiment and indirect Dark Matter studies.
