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 improves the precision of determining the resonance pole position by applying Padé approximants to -scattering amplitudes while enforcing correct threshold behavior, thereby validating the method as a simple and effective tool for extracting resonance poles.
This paper presents a comparative analysis of hadronic secondary fluxes from the upcoming T Coronae Borealis outburst, demonstrating that while external shock models yield detectable gamma rays but negligible neutrinos, a magnetic reconnection scenario near the white dwarf surface produces a robust, early-arriving neutrino signal detectable by IceCube and KM3NeT, offering a unique temporal signature to distinguish between particle acceleration mechanisms.
This paper presents a unified framework that combines GPD-based contributions and vector-meson exchange to fit nucleon electromagnetic form factors, subsequently deriving stable, global Padé-based analytic parametrizations that accurately describe nucleon structure across a wide range of momentum transfers.
This paper presents a systematic analysis of fall-apart decays for fully-strange tetraquark states, suggesting that most have narrow widths and proposing that the newly observed and resonances correspond to specific low-lying -wave and -wave tetraquark candidates, respectively, which can be further investigated through their dominant decay channels.
This paper proposes a novel Standard Model extension based on a double right-handed gauge symmetry that naturally explains fermion mass hierarchies through distinct tree-level and radiative generation mechanisms, accounts for neutrino mass patterns via combined seesaw processes, and provides a viable scalar singlet dark matter candidate consistent with experimental constraints and collider prospects.
This paper introduces Thermal Resonant Leptogenesis (TRL), a new mechanism where thermally-induced Higgs decays generate dominant resonant lepton-doublet flavor coherences to explain the observed baryon asymmetry without requiring quasi-degenerate sterile neutrinos, offering distinct testable predictions for fixed-target and collider experiments.
This paper introduces a differentiable probabilistic programming framework leveraging GPU acceleration and variational inference to efficiently analyze the large model space of astrophysical -ray data, specifically targeting the Galactic Center -ray Excess puzzle while demonstrating a flexible approach for broader astrophysical applications.
This paper proposes a novel cosmological scenario where an initially excessive baryon asymmetry in the early universe triggers the gravitational collapse of Hubble patches into primordial neutron stars with masses as low as 0.1 solar masses, provided that a subsequent large entropy injection later restores the observed baryon asymmetry and preserves standard Big Bang nucleosynthesis predictions.
This paper demonstrates that while multi-axion frameworks can relax theoretical bounds on the QCD axion's photon coupling and allow it to evade detection as a dark matter candidate, they typically predict the existence of a visible axion-like particle that remains accessible to next-generation experiments.
This paper establishes a rigorous, first-principles Euclidean-time prescription for calculating quantum tunnelling rates from initial states carrying conserved Noether charges, unifying direct and steadyon approaches to explain complex saddle points and extending results to systems with both charge and non-trivial energy.
