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 reviews three decades of progress in generalized parton distributions (GPDs), highlighting significant advancements in experimental measurements, sophisticated phenomenological analyses, theoretical refinements, and lattice QCD calculations that collectively enable three-dimensional nucleon tomography and a deeper understanding of the nucleon's mass, spin, and internal forces.
This paper investigates T-odd effects arising from two-photon exchange in semi-inclusive deeply inelastic scattering at low transverse momentum, demonstrating that while the absorptive part of the scattering amplitude is divergent, the resulting physical differential cross-section remains finite and exhibits distinct angular dependencies that offer new avenues for detecting effects beyond the one-photon approximation and searching for new physics.
This paper provides a comprehensive overview of the theoretical foundations and phenomenology of higher-twist effects in QCD, detailing their role in nonperturbative dynamics, their extraction from global DIS analyses, and future experimental opportunities at Jefferson Lab and the Electron-Ion Collider.
By reanalyzing BESII -value data within an unquenched charmonium framework that includes six vector states, this study resolves the puzzling upward mass shift of the by demonstrating that the observed enhancement near 4.19 GeV arises from coherent interference among nearby resonances rather than a genuine shift in the mass itself.
This paper investigates constraints on neutralino dark matter within non-universal gaugino mass SU(5) supersymmetry, finding that while pure wino and higgsino benchmarks are excluded by H.E.S.S. gamma-ray and direct-detection limits, bino-dominated and mixed bino-wino scenarios remain viable and highlight the complementarity of multi-messenger searches.
This paper employs a semirelativistic potential quark model to demonstrate that the hidden-charm pentaquark states observed by LHCb are predominantly hadronic molecules formed via - and -meson exchanges, successfully identifying the , , and as and bound states while offering a molecular interpretation for the despite a discrepancy in its predicted width.
This paper investigates the structure of the meson by calculating its valence-quark generalized parton distribution functions and form factors using a theoretical framework based on the exponential representation scheme combined with the modified chiral quark model, comparing the results with experimental data and other models.
This paper summarizes the phenomenology of colour sextet baryons in composite Higgs models, detailing their dominant decay channels into top or bottom quarks and establishing collider recasting bounds that exclude masses up to 2.64 TeV.
This paper investigates the phenomenology of spin-1 resonances in composite Higgs models, demonstrating that two neutral and one charged state can mix with Standard Model gauge bosons to allow single production via Drell-Yan processes at the LHC, with masses potentially as low as 1.5 TeV consistent with current data.
This study demonstrates that the reaction, governed by the same -- triangle dynamics as the channel, exhibits no distinct signal due to kinematic suppression of the triangle singularity and destructive interference between tree-level and loop amplitudes, thereby validating the model's explanation for the state's production mechanism.
