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 presents a next-to-leading order expansion formula for computing parton distribution functions from current-current correlators, which offer simple renormalization properties and avoid linear power divergences, alongside preliminary numerical results utilizing four-point functions on the lattice.
This paper proposes a novel production mechanism for long-lived dark photons at the LHC via dark radiation from dark matter in decays, demonstrating that this channel can dominate over conventional sources and enable dedicated detectors like FASER2, FACET, and MATHUSLA to probe previously inaccessible regions of parameter space consistent with the observed dark matter relic abundance.
This paper presents a community-informed overview and initial roadmap for the development of Artificial Intelligence in High Energy Physics, drawing on discussions from the 2025 Qingdao workshop to guide future coordinated efforts in China and globally.
This paper demonstrates that quantum loop corrections inevitably link ultralight dark matter's self-interactions to its couplings with matter, allowing stringent astrophysical bounds on repulsive self-interactions to robustly constrain linear couplings to neutrinos and quadratic couplings to electrons and light quarks, often surpassing existing limits from equivalence-principle tests.
This paper extends electroweak baryogenesis to a non-Markovian framework using the Schwinger--Keldysh formalism, demonstrating that memory effects significantly alter CP-violating transport dynamics and the resulting baryon asymmetry while also influencing the stochastic gravitational-wave signal.
This paper predicts that the scalar meson , dynamically generated through final-state interactions, will manifest as distinct peaks in the invariant mass distributions of pairs in both the strong decay and the radiative decay , offering a promising avenue for future experimental verification and precise characterization by facilities like BESIII, Belle II, and STCF.
This paper demonstrates that a first-order phase transition at the end of inflation, occurring in a spectator scalar sector dominated by Coleman-De Luccia tunneling, can successfully generate the observed dark matter abundance through a combination of direct particle production from bubble collisions and the subsequent decay of spectator particles.
This paper presents and validates the analytic all- expressions for four-loop non-singlet splitting functions in QCD, confirming their consistency with fixed- results and utilizing them to finalize analytical forms for the four-loop gluon virtual anomalous dimension and next-to-next-to-next-to-leading logarithmic threshold-resummation coefficients, while highlighting a new structure in small- quartic-Casimir contributions.
This paper investigates QCD axion physics within 4D F-theory MSSM models by deriving axion couplings and potentials from a top-down perspective, ultimately constraining the Kähler moduli space of specific base threefolds to predict a QCD axion mass of approximately eV and a decay constant near GeV.
This paper introduces a modification of QCD sum rules using Euclidean time correlators in coordinate space instead of Borel transforms, demonstrating that while nucleon mass and residue can be roughly estimated, this approach suffers from significantly larger uncertainties and a lack of a stable working window compared to traditional Borel sum rules.
