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.

Transfer Learning for Neutrino Scattering: Domain Adaptation with GANs

This paper demonstrates that transfer learning with Generative Adversarial Networks effectively extrapolates physics information from synthetic neutrino-carbon scattering data to related processes like neutrino-argon and antineutrino-carbon interactions, significantly outperforming models trained from scratch and maintaining high accuracy even with limited statistics.

Impact of QCD Energy Evolution on Observables in Heavy-Ion Collisions

This study demonstrates that incorporating QCD small-xx energy evolution (JIMWLK) into the IP-Glasma initial state framework significantly alters key heavy-ion collision observables, such as particle multiplicities and flow correlations, highlighting the critical necessity of nonlinear QCD evolution for accurately modeling early-stage dynamics and extracting quark-gluon plasma transport properties.

SL(2N,C) Yang-Mills Theories: Direct Internal Forces and Emerging Gravity

This paper proposes a four-dimensional gauge-gravity unification based on $SL(2N,C)$ Yang-Mills theory where spontaneous symmetry breaking and tetrad condensation induce Einstein-Cartan gravity and generate three composite fermion families, with anomaly matching uniquely selecting N=8N=8 to yield the SL(16,C)SL(2,C)×SU(8)SL(16,C)\rightarrow SL(2,C)\times SU(8) chain.

Perturbative limits on axion-SU(2) gauge dynamics during inflation from the energy density of spin-2 particles

This paper demonstrates that the perturbative treatment of axion-SU(2) gauge dynamics during inflation breaks down when the energy density of produced spin-2 particles exceeds that of the background field, a condition that often occurs prior to the strong backreaction regime and necessitates non-perturbative lattice simulations for reliable analysis.

Heavy dark matter in rapidly evolving massive stars

This study demonstrates that heavy dark matter captured by rapidly evolving massive stars, particularly the first stars, can significantly alter their lifecycles through thermalization, annihilation equilibrium, or self-gravitating collapse into black holes, with capture rates critically dependent on stellar composition, evolutionary stage, and the local dark matter velocity distribution.
