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.

Effect of Cosmic Neutrino Background on the Dark Matter Self-interaction via Neutrino force

This paper demonstrates that the Cosmic Neutrino Background significantly alters dark matter self-interactions mediated by neutrino forces through a screening effect arising from the interplay of vacuum and background potentials, thereby reshaping viable coupling ranges and suppressing Sommerfeld enhancement for dark matter annihilation.

Phenomenology of a Kinetic Higgs Portal

This paper investigates the phenomenological implications of non-standard momentum dependencies in a Z2\mathbb{Z}_2-symmetric Higgs portal, particularly within Composite Scalar Dark Matter models, demonstrating how future lepton colliders like FCC-ee can probe these hidden sector interactions through precision measurements of Higgs correlations and radiative corrections.

Non-perturbaitve effects for the isoscalar light vector ω\omega-meson in charmed meson semileptonic decays

Motivated by recent BESIII data, this study employs QCD light-cone sum rules to calculate the form factors, branching fractions, and various angular observables for the semileptonic decay D+ω+νD^+\to \omega \ell^+\nu_{\ell}, finding results that are in good agreement with experimental measurements from BESIII and CLEO.

Testing lepton non-unitarity with the next generation of Germanium-based CEν\nuNS reactor experiments

This paper investigates how deviations from unitarity in the leptonic mixing matrix, arising from either heavy or light sterile neutrinos, modify coherent elastic neutrino-nucleus scattering and elastic neutrino-electron scattering, presenting sensitivity projections for a future upscaling of the CONUS+ experiment that demonstrate its potential to probe TeV-scale new physics.

BB-meson decay width up to 1/mb31/m_b^3 corrections within and beyond the Standard Model

This paper presents a complete calculation of BB-meson decay widths up to 1/mb31/m_b^3 corrections within and beyond the Standard Model by deriving analytic expressions for all matching coefficients of two-quark operators and previously missing weak-annihilation contributions, thereby finalizing the theoretical framework for non-leptonic bb-quark decays relevant to BB-meson lifetimes and addressing tensions in QCD factorization.

NuSTAR as an Axion Helioscope: probing axion-nucleon and axion-electron couplings

This paper utilizes NuSTAR solar X-ray observations from the 2020 solar minimum to derive significantly improved 95% confidence level limits on axion-nucleon and axion-electron couplings for axion masses below 10610^{-6} eV, establishing solar X-ray monitoring as a powerful method for axion searches.
