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 demonstrates that top-quark pair production measurements at the FCC-ee, utilizing matrix-element-based discriminants and IDEA detector simulations, can constrain heavy new physics scales up to 30 TeV in single-operator fits and up to 5 TeV in global fits, offering complementary sensitivity to High-Luminosity LHC prospects.
This paper proposes a stable dark matter model based on the topological defects arising from the symmetry breaking of SU(3) to SO(3), which predicts specific mass ratios for a dark octet, satisfies cosmological and astrophysical constraints via co-annihilation and self-interactions, and offers testable signatures through future collider, gravitational wave, and radio observations.
This paper reanalyzes a reported 43 GeV gamma-ray line in galaxy clusters and concludes that while the excess is a robust statistical feature, its broad spatial morphology and the resulting conflict with Galactic halo constraints make a dark matter interpretation unlikely, suggesting instead that it is a chance fluctuation or an artifact of background mismodeling.
This paper investigates nuclear responses for WIMP-nucleus scattering in dark matter direct detection, specifically focusing on inelastic channels in Xe and Xe isotopes using relativistic configuration-interaction density functional theory to demonstrate that inelastic contributions can significantly dominate elastic ones and substantially impact the interpretation of detection results.
By stacking 145,087 DESI spectra paired with foreground galaxy groups, researchers found no evidence for multi-state dark matter absorption lines, thereby establishing stringent upper limits on magnetic dipole transition cross-sections for MeV-scale dark matter in a parameter space inaccessible to current cosmological and direct detection experiments.
This paper presents a feasibility study demonstrating how recent advances in quantum-sensing technologies can enable stringent comparisons between theory and experiment for contact-free transitions in muonic atoms, thereby probing new physics in spin-independent muon-proton interactions and disentangling fundamental constants from beyond-Standard-Model searches.
This paper investigates exclusive semileptonic and nonleptonic decays within the Standard Model using a light-front quark model enhanced by Bethe-Salpeter formalism to account for nonvalence contributions, yielding branching fractions and asymmetry ratios that are consistent with current experimental measurements.
This paper provides a comprehensive review of glueballs—colour-singlet bound states of gluons predicted by Quantum Chromodynamics—covering their theoretical properties across various models, the complexities of mixing with quark-antiquark states in full QCD, decay mechanisms, experimental production, and the current status of candidate identification in different quantum number sectors.
This paper reviews recent Drell-Yan measurements of transverse-momentum dependent distributions (TMDs) and discusses future prospects for accessing generalized parton distributions (GPDs) via exclusive pion-induced Drell-Yan processes at J-PARC to further explore nucleon spin and test TMD/GPD universality.
This paper proposes and validates a single empirical nuisance parameter, , to address the lack of topology-transfer capabilities in standard GENIE simulations for liquid-argon neutrino analyses, demonstrating through MicroBooNE data that this parameter effectively captures near-threshold proton mismodelling effects with a statistically significant constraint of .
