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.

The effect of Coulomb interactions on relic neutrino detection via beta decaying impurities in (semi)metals

This paper investigates how Coulomb interactions between electrons in β\beta-decaying impurities and their solid-state environment affect the energy resolution and visibility required for detecting the cosmic neutrino background, analyzing scenarios ranging from completely suppressed hybridization via dielectric spacers to cases where hybridization is treated perturbatively.

Carrier-envelope phase and pulse shape effects on vacuum pair production in asymmetric electric fields with bell-shaped envelopes

This study demonstrates that the carrier-envelope phase and pulse shape of asymmetric electric fields significantly influence electron-positron pair production, with specific configurations capable of enhancing pair density by two to three orders of magnitude through multiphoton dominance and optimized envelope steepness.

Universal Description of Decoherence in Scale-Invariant Environments

This paper proves that under fundamental physical principles, any quantum system coupled to a scale-invariant environment decoheres uniquely as an "unparticle bath" characterized by a single scaling dimension, a framework validated by experimental data and unified across diverse physical regimes from condensed matter to cosmology.

Lorentz and CPT violation and the hydrogen and antihydrogen molecular ions III -- rovibrational spectrum and the non-minimal SME

This paper presents a comprehensive derivation of the rovibrational spectrum for hydrogen and antihydrogen molecular ions within the non-minimal Standard-Model Extension, demonstrating how high-precision spectroscopy of these systems can test Lorentz and CPT symmetry with sensitivities up to O(1017)O(10^{-17}) by analyzing quantum number dependencies and temporal variations.

Probing inelastic sub-GeV dark matter at the DUNE near detector

This paper investigates the sensitivity of the DUNE near detector's liquid argon cube to sub-GeV inelastic dark matter within a UV-complete framework featuring a dark Higgs mechanism, demonstrating its unique ability to probe parameter space consistent with the observed relic abundance, particularly in regions where traditional decay-based searches are ineffective.

Theoretical modeling of charged current νμ(νˉμ)40Ar\nu_\mu(\bar\nu_\mu)-^{40}Ar DIS at DUNE energies

This paper presents a theoretical study of charged current νμ(νˉμ)\nu_\mu(\bar{\nu}_\mu)-induced deep inelastic scattering on 40Ar^{40}\mathrm{Ar} at DUNE-relevant energies, utilizing a microscopic framework with nuclear medium effects and NNLO QCD corrections to compute nuclear structure functions and differential cross sections.
