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 calculates the form factors for and transitions using three-point QCD sum rules with various condensate contributions, and subsequently predicts the decay widths and branching ratios for several two-body nonleptonic decay processes to provide insights into heavy-quark dynamics.
This paper proposes that axion dark matter induces electromagnetic radiation in conductors via the chiral magnetic effect, demonstrating that existing cavity experiments can constrain the axion-electron coupling to and suggesting that replacing copper walls with carbon-based conductors could enhance sensitivity to over a wider mass range.
This paper proposes a novel mechanism for primordial Dirac leptogenesis occurring during the post-inflationary reheating phase, where an inflaton-generated asymmetry is transferred to chiral neutrinos and subsequently to baryons via sphalerons, offering a testable prediction for the effective number of relativistic species () while naturally accommodating small neutrino Yukawa couplings.
This paper investigates the complementarity between future gravitational wave observations and high-luminosity/high-energy LHC di-Higgs searches in probing a first-order electroweak phase transition driven by specific dimension-6 SMEFT operators.
This paper proposes a gauged benchmark model featuring a compressed dark fermion spectrum and a small mixing angle to suppress direct detection constraints, demonstrating that a novel conversion mechanism effectively generates the observed dark matter relic density while remaining consistent with current collider and cosmological limits.
This paper demonstrates that placing quantum field theories on asymptotically locally Euclidean (ALE) spaces, such as the Eguchi-Hanson manifold, reveals 't Hooft anomalies invisible on standard closed four-dimensional manifolds due to boundary torsion and nontrivial cohomology, thereby imposing stricter constraints on the infrared realization of asymptotically free gauge theories.
This paper investigates the sensitivity of the upcoming Electron-Ion Collider to purely electrophilic axion-like particles and bosons in the GeV mass range, demonstrating that the facility can significantly extend exclusion limits on these new physics scenarios through tri-electron and photon final state analyses.
This paper employs three-point QCD sum rules to systematically analyze the spin- weak transitions of doubly charmed baryons, calculating form factors and predicting the semileptonic decay rates of and to singly charmed baryons to aid in understanding heavy baryon dynamics and searching for new physics.
This paper calculates the total diffuse boosted cosmic neutrino background arising from all scattering channels between cosmic rays and relic neutrinos, demonstrating that current and future neutrino telescopes like IceCube-Gen2 have the sensitivity to detect the expected cosmological overdensity of the cosmic neutrino background.
This paper identifies unphysical kinematic features in EvtGen simulations of semileptonic decays involving resonances caused by neglected phase-space factors and proposes a reweighting method to correct the affected hadronic invariant mass distributions.
