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.

Gravitational Wave Signals in a Promising Realization of SO(10) Unification

This paper investigates gravitational wave signals in a non-supersymmetric SO(10) grand unified model, demonstrating that the first step of symmetry breaking can induce a first-order phase transition producing a detectable background, though current experimental sensitivity remains insufficient for observation.

The Scotogenic Model with Two Inert Doublets: Parameters Space and Electroweak Precision Tests

This paper investigates a scotogenic extension of the Standard Model with two inert doublets and three singlet Majorana fermions, identifying viable parameter spaces for radiative neutrino mass generation and dark matter while revealing that approximately 60% of these regions are excluded by recent CMS measurements of the WW boson mass due to constraints on the oblique parameter ΔT\Delta T.

Dark photon dark matter constraints at the Taiwan axion search experiment with haloscope

By re-analyzing data from the Taiwan Axion Search Experiment with Haloscope (TASEH) while accounting for scanning timing information, the authors derive world-leading constraints on dark photon dark matter that exceed naive rescaling limits by a factor of two and demonstrate the critical importance of avoiding magnetic-field-only vetoes to prevent discarding valid dark photon signals.

Truncation uncertainties for accurate quantum simulations of lattice gauge theories

This paper presents a new formalism for estimating truncation errors in the electric basis of lattice gauge theory simulations on quantum computers, leveraging Hilbert space fragmentation to demonstrate that errors decay factorially with field truncation, thereby improving previous error estimates by a factor of up to 1030610^{306} for models like the Schwinger model and pure U(1) gauge theory.

Constraints on the varying electron mass and early dark energy in light of ACT DR6 and DESI DR2 and the implications for inflation

Motivated by the Hubble tension, this study utilizes DESI DR2 and ACT DR6 data to constrain the varying electron mass and early dark energy models, finding a slight preference for a varying electron mass while ruling out significant early dark energy contributions, and subsequently identifying distinct inflationary scenarios favored by each model.
