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 provides a theoretical review of recent progress in understanding the bulk properties of the quark-gluon plasma and the production of light and strange hadrons in heavy-ion collisions, emphasizing the central role of relativistic hydrodynamics and improved constraints on initial states and transport properties.
This paper proposes that while current data favor a flavor-singlet hybrid interpretation for the glueball candidate, specific resonance-resolved decay ratios can definitively distinguish between compact-tetraquark, hybrid, and trigluon-glueball structures, transforming the ambiguity of its constituent nature into a testable experimental question.
This paper reviews the current status of axions and axion-like particles, focusing on the challenges regarding their mass generation and exploring potential connections to other unresolved issues within the Standard Model, particularly in the context of extending the parameter space for solving the Strong CP problem.
This paper introduces a 2026 open-source electronic edition of D. A. Varshalovich's classic "Quantum Theory of Angular Momentum," which retains the original 1988 content while integrating modern enhancements such as Python-based symbolic tools, AI-verified results, and interactive digital features under a CC-BY 4.0 license.
This paper proposes that the single 248-keV nuclear recoil event observed by the LUX-ZEPLIN experiment can be explained by exothermic dark matter downscattering from a pseudo-Dirac excited state with a splitting of approximately -350 keV, a model that naturally accounts for the event's energy, evades standard search constraints, and predicts a distinct signal in argon-based detectors that would definitively distinguish it from endothermic interpretations.
This paper presents a closed-form perturbative framework demonstrating that constant, flavour-blind Planck-scale mass corrections induce a baseline-dependent phase drift in vacuum neutrino oscillations, offering a distinct observable for distinguishing quantum-gravity effects from conventional matter interactions in next-generation experiments.
This paper develops a manifestly gauge and Lorentz invariant perturbative framework to demonstrate that electrically charged states in scalar QED are superselected by the orientation of their Wilson-line dressings due to "cloud orthogonality," while within a single sector, the absence of a sharp mass pole reveals an infraparticle structure characterized by a power-law spread in proper time.
This paper utilizes an instantaneous Bethe-Salpeter framework combined with a relativistic decay model to demonstrate that open-charm decays of the -- system act as momentum-space nodal filters, where channel-dependent overlap kernels reveal distinct wave-function structures and cancellation patterns that explain anomalous width ratios and amplitude zeros.
This paper derives the electronic dielectric function for bulk superconductors within the BCS framework and demonstrates that the standard Lindhard approximation remains a robust model for dark matter direct detection when energy depositions exceed five times the superconducting gap.
This paper proposes a radiative double inverse seesaw model within an alternative gauged framework that naturally generates tiny neutrino masses and stabilizes dark matter candidates, with a comprehensive analysis favoring the fermionic dark matter scenario over the bosonic one due to stringent constraints from direct detection experiments.
