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.

One Event, Two Frontiers: From LZ to LHC

This paper investigates whether the 248 keV nuclear-recoil event observed by the LUX-ZEPLIN experiment can be explained by dark matter interactions, finding that for most effective models, LHC monojet constraints exclude this interpretation for dark matter masses below approximately 1 TeV, thereby challenging the viability of future direct detection probes in this parameter space.

Functional renormalization of QCD in 1+11 + 1 dimensions: four-fermion interactions from quark-gluon dynamics

This paper investigates Quantum Chromodynamics in two spacetime dimensions using the Functional Renormalization Group to derive flow equations for gauge and quark parameters, demonstrating a transition from ultraviolet super-renormalizability to a strongly coupled infrared regime while establishing a foundation for future studies of bound state spectra.

Fluid perturbations from expanding bubbles in first-order phase transitions

This paper presents a refined template for the velocity power spectrum generated by expanding bubbles during first-order phase transitions, demonstrating that spectral breaks are determined by velocity profile discontinuities rather than geometric scales and providing these results via the CosmoGW Python package for gravitational wave studies.

CP-violation or Nuclear Excitation: Reviewing the Role of Neutrino Interaction Model Uncertainties on Accelerator-Based Neutrino Oscillation Measurements

This paper reviews the critical impact of uncertainties in neutrino-nucleus interaction modeling on accelerator-based oscillation measurements and outlines the theoretical and experimental strategies required to mitigate these systematic errors for next-generation experiments.
