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 introduces a novel Monte Carlo simulation framework and a Neural Sorter Mamba Network to analyze Lund Jet Plane representations, successfully demonstrating the ability to distinguish between different dark gauge symmetries based on their unique radiation patterns while remaining robust against non-perturbative hadronization uncertainties.
This paper utilizes QCD sum rules with explicit SU(3)-flavor breaking effects to demonstrate that the magnitude of mass shifts in hidden-charm-strange tetraquarks serves as a structural discriminator, distinguishing between compact and molecular-like color-octet configurations.
This paper investigates neutrino mixing within the Einstein–Cartan framework, demonstrating that constant and time-dependent axial torsion induces spin-dependent effective masses and energies that modify both oscillation frequencies and amplitudes in a quantum-field-theoretic analysis, with the most pronounced deviations from standard quantum-mechanical descriptions occurring in the nonrelativistic regime.
This paper investigates the impact of dark photon-induced cooling on red dwarfs by combining stellar evolution simulations with precise mass-radius measurements from eclipsing binaries, ultimately deriving competitive constraints on dark photons that surpass solar limits in significant regions of the parameter space.
This paper investigates the prospects for detecting heavy Majorana neutrinos at the 14 TeV LHC within the type-I seesaw framework, demonstrating that collider sensitivity to light-heavy neutrino mixing is strongly correlated with the ratio of same-sign to opposite-sign dilepton events and the associated CP asymmetry, particularly for neutrino masses between 50 and 100 GeV.
This paper presents the first calculation of mixed QCD-electroweak corrections to Higgs boson pair production in the quark-antiquark channel, deriving fully analytic virtual amplitudes and implementing them in the POWHEG-BOX framework to reveal significant shape modifications in differential cross sections, particularly near the production threshold.
This paper investigates the discovery potential of the Forward Physics Facility at the 100 TeV FCC-hh for heavy neutral leptons and bosons within anomaly-free chiral extensions of the Standard Model, demonstrating that the facility can significantly extend sensitivity to light, long-lived particles beyond current and proposed experiments through various production and decay channels.
This paper investigates non-logarithmic heavy-quark mass effects in the two-jet limit of the Energy-Energy Correlation by introducing a novel partial event fraction calculable via real emission diagrams in four dimensions and proposing an improved factorization scheme that ensures a smooth massless limit through an angle-dependent coefficient function.
This paper demonstrates that damped heavy neutrino-antineutrino oscillations significantly alleviate the suppression of lepton number violation in symmetry-protected pseudo-Dirac heavy neutral leptons at hadron colliders, while showing that combining lepton-number-blind and lepton-number-violating searches can distinguish these models from the double-Majorana limit despite the sensitivity challenges posed by small mass splittings.
This paper presents a systematic quantum treatment of a new phenomenon where transverse matter currents induce neutrino spin and spin-flavor oscillations, incorporating both standard and nonstandard interactions and applying the findings to a binary neutron star merger scenario.
