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.

Constraints on Self-Interacting Fuzzy Dark Matter from the Stellar Kinematics of the Dwarf Galaxy Leo II

This study uses stellar kinematics from the dwarf galaxy Leo II to constrain the two-dimensional parameter space of self-interacting fuzzy dark matter, revealing that attractive (repulsive) self-interactions lead to more concentrated (diffuse) density profiles and establishing 95% confidence lower limits on the particle mass within the range of (110)×1022eV(1-10)\times10^{-22}\,\mathrm{eV} for interaction strengths up to fa11014GeV1f_a^{-1}\lesssim 10^{-14}\,\mathrm{GeV}^{-1}.

Investigating the mass spectra of 1F1F-wave singly heavy ΣQ\Sigma_{Q}, ΞQ\Xi^{\prime}_{Q}, and ΩQ\Omega_{Q} baryons

This paper predicts the mass spectra of experimentally unobserved 1F1F-wave singly heavy ΣQ\Sigma_{Q}, ΞQ\Xi^{\prime}_{Q}, and ΩQ\Omega_{Q} baryons (Q=c,bQ=c, b) by employing a quark-diquark configuration within a Regge trajectory model and calculating spin-dependent mass shifts via a 6×66\times 6 matrix to guide future experimental searches.

Collective response and noise of a levitated ferromagnet lattice for ultralight dark matter detection

This paper proposes a scalable lattice of levitated ferromagnets for ultralight dark matter detection, demonstrating that while dipole-dipole interactions create a narrow thermal-noise blind zone, the collective system significantly enhances sensitivity to axion-electron, dark-photon, and axion-photon couplings compared to single-ferromagnet detectors.

A flow-matching generative model for event-by-event jet-induced hydro response in high-energy heavy-ion collisions

This paper introduces a Flow Matching generative model that rapidly and accurately predicts final-state hadron spectra from jet-induced hydrodynamic responses in heavy-ion collisions, achieving a six-order-of-magnitude computational speedup over traditional full simulations while preserving key physical properties.

Charged-current neutrino opacity within the relativistic Hartree-Fock framework for astrophysical simulations of core-collapse supernovae and binary neutron star mergers

This paper introduces a relativistic Hartree-Fock framework with momentum-dependent nuclear interactions to improve the calculation of charged-current neutrino opacities for astrophysical simulations, revealing significant discrepancies and substantial shifts in medium-dependent modifications compared to commonly used relativistic mean-field models.
