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 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.
This paper presents a unified framework for simulating exclusive boson production in electron-proton collisions at the future Electron-Ion Collider, which integrates phenomenological amplitudes for various particles to provide precise kinematic predictions that surpass traditional flux-factorized approximations, particularly for multi-differential observables and forward-proton acceptance studies.
This paper demonstrates that a future 10 TeV muon collider can significantly surpass current and projected LHC and FCC-ee limits by using detailed simulations of Higgs and top quark production processes to constrain dimension-6 SMEFT operators and probe new physics scales far beyond the LHC's reach.
This paper refutes claims that quantum damping of cosmological shear in modified loop quantum cosmology is non-generic by demonstrating that previous counterexamples relied on unphysical initial conditions, and establishes that for physically admissible three-dimensional contracting universes, shear damping is a robust feature leading to an isotropic attractor and classicalization.
Using the complete Borexino dataset from 2007 to 2021, researchers established the most stringent experimental limits to date on the lifetime of nuclei against Pauli exclusion principle-forbidden transitions, setting lower bounds ranging from to years for various decay channels and deriving extremely tight upper limits on the relative strengths of such non-Paulian processes.
This paper outlines a modern, transparent, and methodologically robust effort to improve the precision and reliability of nuclear charge radii determinations by integrating complementary experimental techniques with advanced theoretical frameworks.
