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.

Neutrino masses, anomalous magnetic moments and dark matter with vector-like fermions and an inert scalar doublet

This paper proposes a beyond-the-Standard-Model framework incorporating vector-like fermions and an inert scalar doublet protected by a Z2Z_2 symmetry to simultaneously explain neutrino masses, the anomalous magnetic moments of electrons and muons, and dark matter, while remaining consistent with experimental constraints and offering testable LHC signatures.

Ultralight dark matter detection with trapped-ion interferometry

This paper proposes using a single trapped ion prepared in a spin-motion entangled "Schrödinger cat" state as a matter-wave interferometer to detect ultralight dark matter, demonstrating that this approach offers parametrically enhanced sensitivity to probe unexplored regions of dark-photon and axion-like particle parameter space in the 101510^{-15} to 101410^{-14} eV mass window.

Quantum-Enhanced Dark Matter Search Using Cat States

This paper reports the first experimental demonstration of using four-component cat states in a superconducting microwave cavity to search for dark photons, achieving an 8.1-fold signal enhancement and setting an unprecedented constraint on the kinetic mixing angle of ϵ<7.32×1016\epsilon < 7.32 \times 10^{-16} near 6.44 GHz.

Scale dependence improvement of the quartic scalar field thermal effective potential in the optimized perturbation theory

This paper introduces a "variational renormalization group" framework that combines renormalization group improvement with optimized perturbation theory to significantly reduce renormalization scale dependence in the thermal effective potential of scalar λϕ4\lambda \phi^4 theory, thereby enhancing the precision of critical temperature and pressure predictions for applications in cosmology and condensed matter physics.

Higgs pair production in gluon fusion to higher orders in Higgs Effective Field Theory

This paper investigates Higgs pair production via gluon fusion within the Higgs Effective Field Theory (HEFT) framework, demonstrating that a consistent power counting at next-to-leading order requires the inclusion of higher-dimensional operators and necessitates a critical re-evaluation of the kinematic benchmark scenarios used in experimental di-Higgs searches.

Vanishing Compactness Gap and Fermionic Compact Dark Matter in Hořava-Lifshitz Gravity

This paper demonstrates that in Hořava-Lifshitz gravity, the compactness gap between black holes and neutron stars can vanish for fermionic objects above a certain mass threshold, potentially blurring the classification of LIGO-Virgo-KAGRA detections and suggesting that fermions with a mass of approximately 40 GeV could constitute compact dark matter.
