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 investigates the emission of Cherenkov plasmons by primordial neutrinos in a nonrelativistic lepton plasma, deriving the energy emission rate to demonstrate that this mechanism can efficiently cool neutrino clusters formed in the early universe through interactions with a hypothetical light scalar boson.
This paper presents an analytic framework treating finite-mass sterile neutrinos as a dynamical cosmological fluid with a time-dependent equation of state, demonstrating how their suppressed thermalization and evolving pressure impact the expansion history and shift the matter-radiation equality epoch beyond the standard constant approximation.
This paper proposes a systematic framework using maximum-entropy reweighting and precision moments of energy flow polynomials to upgrade parton-shower event samples with higher-accuracy theoretical constraints, thereby restoring physical behavior and improving predictions across a broad range of observables while preserving full event-level exclusivity.
This paper investigates how the memory-burden effect, which delays primordial black hole evaporation, alters the Lyman- constraints on non-cold dark matter produced by these black holes by modeling the resulting dual velocity-dispersion populations and determining the viable parameter space for such scenarios.
This paper presents the first quantitative study using 15 years of Fermi-LAT data to establish stringent limits on dark matter decay lifetimes by analyzing the unique gamma-ray signal produced when dark matter decay electrons and positrons inverse-Compton scatter solar photons in the inner heliosphere.
This paper refines theoretical predictions for light-by-light scattering by improving two-loop helicity amplitudes with asymptotic expansions and Coulomb resummation, providing state-of-the-art Standard Model cross-section calculations and a new Monte Carlo event generator named LbLatNLO.
This paper presents generalized predictions for the optical and infrared electromagnetic signatures of optically thick mirror star nuggets by solving stellar structure equations and characterizing their emission spectra, thereby providing a comprehensive framework to distinguish these objects from regular stars in existing and future astronomical catalogues.
This paper presents expanded lecture notes from a 2025 training school that explore the detection of axions, axion-like particles, and high-frequency gravitational waves using compact objects such as neutron stars and white dwarfs, including discussions on superradiance and practical exercises.
This paper proposes a Pati-Salam-based UV completion of the Standard Model that simultaneously solves the strong CP problem via the Nelson-Barr mechanism, corrects fermion mass relations for the heaviest generations, and predicts a distinctive neutron decay mode () testable by upcoming nucleon-decay experiments.
This paper presents continuum-estimated (2+1)-flavor lattice QCD results demonstrating that the baryon-electric charge correlation serves as a sensitive magnetometer for strong magnetic fields, while also mapping the equation of state up to and constructing detector-compatible observables to bridge theoretical predictions with experimental heavy-ion collision data.
