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.

Cosmological phase transitions: from particle physics to gravitational waves, semi-analytically

Motivated by recent pulsar timing array evidence for a stochastic gravitational wave background, this paper demonstrates that a full semi-analytical pipeline can accurately predict gravitational wave spectra from supercooled first-order phase transitions in a U(1)U(1)^\prime conformal extension of the Standard Model, thereby enabling efficient exploration of early Universe dynamics without relying on computationally intensive simulations.

The Dark Side of the Moon: Listening to Scalar-Induced Gravitational Waves

This paper investigates how the collapse of large-amplitude primordial curvature perturbations into planetary-mass primordial black holes generates a detectable scalar-induced gravitational wave background in the μ\muHz range, deriving projected constraints on such black hole populations from future Lunar and Satellite Laser Ranging data while considering the electroweak phase transition and recent HSC microlensing observations.

Search for Cosmic-Ray Produced Dark Meson via the U(1)DU(1)_\text{D} Portal at JUNO

This paper investigates the potential of the JUNO experiment to detect sub-GeV dark mesons produced by cosmic rays in the atmosphere via a U(1)DU(1)_\text{D} vector portal, utilizing a modified Quark Combination Model for hadronization and GENIE for interaction simulation to establish projected 90% C.L. sensitivity limits on the dark gauge coupling for various dark sector masses.
