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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes a novel method using linear regression through the origin on Principle of Maximum Conformality (PMC) scale-invariant series to reliably estimate unknown one-order higher QCD corrections, demonstrating its effectiveness and superior predictive stability through the application to the ratio.
This paper investigates two models of interacting scalar fields in Einstein scalar Gauss-Bonnet gravity as unified dark energy and dark matter candidates, demonstrating that while they align with current supernova data and the CDM model, they show a statistically significant preference over CDM when incorporating future Roman Space Telescope mock data at higher redshifts.
This paper systematically investigates and calculates the decay rates of baryon-number-violating nucleon decays into three leptons mediated by noncontact dimension-6 operators, establishing stringent new bounds on these processes that significantly revise previous estimates and improve upon existing experimental limits.
This paper proposes a TeV-scale quark-lepton symmetric Pati-Salam model featuring a softly broken symmetry that suppresses tree-level flavor violations, allowing a leptoquark gauge boson to be as light as 1.1 TeV (though LHC constraints on associated bosons push the limit to 4.3 TeV) while predicting distinctive signatures like vector-like down-type quarks with baryon number and specific neutrino mass generation mechanisms.
Using a double-dilaton Holographic QCD model with a non-perturbative running strong coupling, this study computes neutral and charged pion form factors in the intermediate-energy region to explain experimental deviations from asymptotic behavior and demonstrate that non-perturbative effects persist at higher energy scales than previously thought.
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.
