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.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes a novel two-loop mechanism for low-scale leptogenesis driven by resonant thermal lepton-flavour coherences, which successfully generates the matter-antimatter asymmetry for both Dirac and Majorana singlet neutrinos with GeV-scale masses without requiring significant mass degeneracy.
This paper investigates the classical stability of a non-topological string in the minimal 331 model derived from an $SU(6)$ toy model and concludes that the string is only stable near the semilocal limit, suggesting such defects are unlikely to exist in unified theories based on $SU(N>5)$ Lie algebras.
This paper introduces a novel MERA-inspired tensor network autoencoder for collider jet anomaly detection, demonstrating that its locality-preserving hierarchical structure and disentangling layers provide a superior inductive bias for reconstructing jet data compared to dense and tree-based architectures, particularly under strong compression.
This paper demonstrates that a non-supersymmetric model extended with vector-like fermions and additional scalar fields can simultaneously explain the observed 125 GeV Higgs signal strengths and the 95 GeV excesses reported by LEP and CMS through a systematic analysis of mixed neutral CP-even Higgs states.
This paper demonstrates that quantum gravitational memory-burden effects suppress the high-energy tail of Hawking radiation from evaporating primordial black holes, thereby reducing their total luminosity and systematically weakening the constraints on their dark matter fraction derived from IceCube neutrino observations.
This paper calculates direct detection constraints on inelastic Dirac dark matter with a scalar mediator and leptophilic couplings, demonstrating that the p-wave velocity suppression of annihilation opens viable MeV-GeV mass parameter space and that liquid-xenon experiments like XENON1T, PandaX-4T, and LZ can constrain sub-MeV mass splittings via spin-independent dark matter-electron scattering.
This paper investigates the internal structure of light pseudoscalar mesons (pion and kaon) using spin-improved power-law wave functions to calculate various distribution functions and form factors, finding that quarks and antiquarks carry only 41% of the longitudinal momentum at 16 GeV² while the predicted electromagnetic charge radii and vector form factors align well with experimental data.
This paper evaluates pion-induced QED radiative corrections to the inverse beta decay cross section using heavy baryon chiral perturbation theory, demonstrating that these effects are small enough to enable sub-permille theoretical precision for antineutrino energies above 10 MeV.
This paper demonstrates that incorporating vector-like bottom quarks into the Type-II Two-Higgs-Doublet Model introduces hidden heavy Higgs decay channels that significantly weaken current LHC mass constraints, lowering the exclusion limit for singlet and doublet configurations from approximately 1.5 TeV to as low as 0.98 TeV.
This paper presents a symmetry-preserving approximation for computing light meson spectra that incorporates fully-dressed quark-gluon vertices and demonstrates significantly improved agreement with experimental masses compared to the traditional rainbow-ladder approximation.
