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.

Gauge Symmetry Beyond Perturbation Theory: BRST and anti-BRST Structure, Background Fields, and Infrared Dynamics of Yang--Mills Theory

This paper provides a comprehensive functional framework for non-Abelian gauge theories that utilizes BRST and anti-BRST symmetries within background field gauges to construct a unique, gauge-invariant, and process-independent effective charge for Yang-Mills theory, thereby offering a unified description of its dynamics from the ultraviolet to the infrared regime where dynamical mass generation occurs.

Informational corrections to the early-Universe radiation sector: CET Omega, WIMP freeze-out, and implications for a possible 20 GeV gamma-ray excess

This paper investigates how CET Omega, an informational extension of quantum field theory, introduces a doubly logarithmic correction to the early-Universe radiation density that modifies WIMP freeze-out dynamics, thereby offering a consistent explanation for a tentative 20 GeV gamma-ray excess while remaining compatible with current cosmological constraints.

A Minimal Realization of Radiative Dirac Neutrino Masses via a Non-Invertible Fusion Rule

This paper proposes a minimal one-loop radiative framework for generating Dirac neutrino masses by introducing a scalar leptoquark and non-invertible Ising fusion rules, which alleviates Yukawa hierarchies, realizes a radiative type-I seesaw mechanism, and offers rich, testable phenomenology across various flavor and precision observables.

Classical Gravitational Scattering from the Ultraviolet and the Absence of Calabi-Yau Integrals in the Conservative Sector at O(G5)O(G^5)

This paper demonstrates that Calabi-Yau and complete elliptic integrals do not contribute to conservative gravitational scattering observables at the fifth post-Minkowskian order because the specific ultraviolet singular structures required to generate the necessary logarithmic terms are absent in the classical limit.

Single Pion Production off Free Nucleons: Analysis of Photon, Electron, Pion and Neutrino Induced Processes

This paper presents a unified model for single-pion production across photon, electron, pion, and neutrino interactions that integrates vector and axial-vector form factors for nucleon resonances up to 2 GeV with non-resonant backgrounds to provide a robust framework for analyzing nucleon structure and constraining uncertainties for future accelerator-based neutrino experiments.
