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.

Effects of light-cluster degrees of freedom on collective flows in heavy-ion collisions at FOPI energies

Using a lattice Boltzmann-Uehling-Uhlenbeck transport model with a kinetic approach for light-cluster formation, this study demonstrates that explicitly including dynamical light-cluster degrees of freedom significantly modifies proton collective flows at beam energies below 600 A MeV and successfully reproduces the nucleon-number scaling of light nuclei flows, thereby highlighting the necessity of dynamical cluster treatment for interpreting heavy-ion collision data in this energy regime.

Gaussian curvature and Lyapunov exponent as probes of black hole phase transitions

This paper establishes a purely differential geometric framework demonstrating that the Gaussian curvature of unstable null orbits serves as a direct signature of black hole phase transitions, exhibiting swallowtail-like multivalued behavior during first-order transitions and heat-capacity-like divergence at second-order critical points.

Light Dark Matter Search with 7.8 Tonne-Year of Ionization-Only Data in XENONnT

The XENONnT collaboration reports a blinded search for light dark matter using 7.8 tonne-year of ionization-only data, finding no significant excess over background and setting improved 90% confidence level upper limits on various dark matter interaction cross-sections that push sensitivity closer to the irreducible neutrino background.

Unifying topological, geometric, and complex classifications of black hole thermodynamics

This paper unifies three distinct black hole thermodynamic classification schemes—geometric, topological, and complex—by demonstrating that they are precisely mapped onto one another through the critical point structure of the temperature curve, thereby simplifying the analysis of thermal stability and phase transitions.

Nonequilibrium crossover in the supercritical region from quench dynamics

This paper proposes two novel nonequilibrium dynamical crossover lines in the supercritical region, defined by the peak rate of inhomogeneous structure formation and the turning point of topological defect invasion velocity, respectively, to characterize supercritical subphases by integrating both thermodynamic and dynamical information.
