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.

Signatures of Modified Gravity Below O(10)\mathcal{O}(10) Mpc in a Dynamical Dark Energy Background

This study demonstrates that within a dynamical dark energy (CPL) framework, modified gravity effects capable of suppressing low-redshift structure growth while satisfying CMB constraints must operate on comoving scales smaller than approximately 10 Mpc, a scenario that is moderately preferred over standard Λ\LambdaCDM and further strengthens the case for quintom-like dark energy when combined with current cosmological datasets.

Two photon decay width of the fully charmed tetraquarks: revisiting prospects for ultraperipheral collisions

This paper investigates the production of fully charmed tetraquarks in ultraperipheral heavy-ion collisions by calculating their two-photon decay widths and comparing resonant contributions to continuum backgrounds, revealing that while resonant effects dominate the J/ψJ/ψJ/\psi J/\psi channel, they are subdominant in the diphoton channel, contradicting predictions from a naive vector dominance model.
