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 proposes a "Resonant Sequential Dominance" framework within a Type-I seesaw model featuring a new TBC3 mixing ansatz and an symmetry, which successfully accommodates current neutrino oscillation data and explains the observed baryon asymmetry of the Universe via resonant leptogenesis with lightest right-handed neutrino masses between 0.13 and 230 TeV.
This paper proposes that mysterious transient objects observed in the Palomar Observatory Sky Survey are manifestations of axion quark nuggets (a dark matter candidate), suggesting they are physical cousins of ball lightning and offering a unified framework to explain their characteristics, correlations with UAP reports, and nuclear test timings through established dark matter parameters.
This paper proposes a class of seesaw models where a symmetry-protected texture-zero structure allows for arbitrarily large lepton-number violation in the heavy sector while naturally yielding sub-eV neutrino masses, thereby predicting observable signatures of heavy neutral leptons at current and future experiments.
This paper utilizes the AdS/CFT correspondence to compute the cusp anomalous dimension and the expectation value of two-cusp Wilson loops with transverse separation in strongly coupled super Yang-Mills theory, revealing distinct saddle point contributions and providing insights into TMD soft functions.
This paper presents a comprehensive analysis of COHERENT Ge-mini and TEXONO germanium-based data to validate the Standard Model's weak mixing angle and establish stringent, complementary constraints on neutrino electromagnetic properties, light mediators, and sterile neutral leptons.
This paper demonstrates that paleo-detectors, which record nuclear recoil tracks in ancient minerals, can effectively reconstruct WIMP masses (particularly below 10 GeV and up to 1 TeV) and distinguish between standard and non-standard WIMP-nucleus interactions without requiring directional measurements, offering capabilities that complement and extend beyond conventional direct-detection experiments.
This paper establishes a self-consistent framework using relativistic QCD Sum Rules to simultaneously determine heavy-quark masses and their Hadronic Vacuum Polarization contributions to the muon anomalous magnetic moment, leveraging their intrinsic anticorrelation to achieve unprecedented phenomenological precision and provide a direct diagnostic for residual theoretical uncertainties.
This paper proposes a scenario where heavy neutral leptons with lifetimes typically excluded by Big Bang Nucleosynthesis constraints can evade these limits through large lepton flavor asymmetries that balance neutron-proton conversion, thereby opening a significant parameter space for upcoming accelerator searches like SHiP and linking potential discoveries to the primordial lepton asymmetry of the Universe.
This paper presents the first Bayesian extraction of QCD baryon number susceptibilities from RHIC Beam Energy Scan data, revealing that while second-order susceptibilities align with lattice QCD predictions at low baryon density, they show significant enhancement at higher densities, whereas observed nonmonotonic trends in higher-order fluctuations can be explained by second-order effects and baryon number conservation without requiring irreducible multi-baryon correlations.
This paper proposes a unified framework where quark and lepton mixing parameters, including the Jarlskog invariant, neutrino mass ratios, and CP-violating phases, are precisely described by commensurate structures based on a single hierarchy parameter raised to specific rational powers, resulting in a "digital-clock" quantization of unitarity triangles on a lattice that aligns with current experimental data and yields testable predictions for future neutrino experiments.
