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.

OmniCosmos: Transferring Particle Physics Knowledge Across the Cosmos

This paper demonstrates that the OmniLearned foundation model, originally trained on collider physics data, can successfully generalize across scientific fields to improve predictions of cosmological parameters and halo/galaxy velocities in CosmoBench datasets, marking the first instance of a collider physics model transferring knowledge to cosmology.

Probing Quantum Foundations in Long-Baseline Neutrino Oscillations: Wave Packet Approach from MINOS Data to DUNE Predictions

This paper investigates neutrino flavor oscillations using a wave packet formalism to incorporate finite spatial coherence and decoherence effects, demonstrating that while standard oscillation probabilities may remain indistinguishable from plane-wave predictions, quantum information metrics like Fisher information and triality measures (entanglement, predictability, and visibility) reveal observable imprints of the wave packet structure in both MINOS data and DUNE predictions.

Tidally-enhanced resonances in extreme-mass-ratio inspirals: A tertiary path to chaos

This paper investigates how external tidal fields in extreme-mass-ratio inspirals break spacetime axisymmetry to induce chaotic dynamics and tidal resonances, characterized by distinct plateaus in frequency ratios and phase-locked action-angle variables, which have significant implications for gravitational-wave inference in active galactic nuclei.

Energy-Energy Correlators in ZZ-Tagged Jets in $pp$ Collisions

This paper presents NLL′^{\prime}-accurate predictions for energy-energy correlators inside ZZ-tagged jets in proton-proton collisions, utilizing a framework that combines perturbative evolution with flavor-dependent non-perturbative fragmentation to probe the universality of the confinement scale and the transition from gluon- to quark-dominated fragmentation at forward rapidities.

Leading-Neutron Electroproduction at HERA and the EIC: Sullivan Process, Target Fragmentation, and Pion PDFs

This paper demonstrates that combining Sullivan process and target-fragmentation contributions in Pythia successfully describes HERA leading-neutron data across the full kinematic range, thereby enabling the extraction of pion parton distribution functions at smaller momentum fractions and providing optimized projections for future measurements at the Electron-Ion Collider.

Meson mass spectrum in isospin QCD medium from the Nf=2+1N_f=2+1 quark-meson model

This paper employs the Nf=2+1N_f=2+1 quark-meson model with U(1)AU(1)_A anomaly effects to investigate the phase structures, meson mass spectra, and sound velocities in isospin QCD at finite temperature and density, revealing specific behaviors such as massless charged pions in the superfluid phase and linear growth of neutral pion mass with isospin chemical potential.
