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.

Information-Geometric Perspective on the Hubble Tension: Eigenmode Rotation and Curvature Suppression in wCDM

This paper analyzes the Hubble tension within the wCDM model using an information-geometric framework, revealing that the apparent relief in tension arises not from new physical agreement but from a geometric reconfiguration where varying the dark energy equation of state suppresses Planck's constraint curvature while DESI DR2 data introduces a stiff geometric wall that limits tension relief.

Dissipative spin hydrodynamics in Bjorken flow and thermal dilepton production

This paper investigates boost-invariant spin hydrodynamics with a first-order framework, demonstrating that spin dissipation alters the temperature evolution of the expanding medium and subsequently enhances thermal dilepton production, thereby suggesting dileptons as a viable probe for spin dynamics in the quark-gluon plasma.

Neutron star with dark matter using vector portal

This paper investigates how fermionic dark matter interacting with nucleons via a vector mediator (Z′Z^\prime) alters the equation of state and structural properties of neutron stars, demonstrating that observational constraints on mass, radius, and tidal deformability can limit vector portal parameters while linking astrophysical findings to terrestrial dark matter searches.

Predictions of Modular Symmetry Fixed Points on Neutrino Masses, Mixing, and Leptogenesis

This paper proposes a type III seesaw model within a non-holomorphic modular symmetry framework where Yukawa couplings are fixed at specific modular symmetry points, demonstrating that certain fixed points and their immediate neighborhoods can successfully reproduce observed neutrino oscillation data and the baryon asymmetry of the Universe.

Natural SUSY with mixed axion/axino dark matter

This paper investigates the viability of natural supersymmetry with mixed axion-axino dark matter, demonstrating that scenarios where the axino is the lightest supersymmetric particle can satisfy dark matter abundance constraints across specific ranges of the Peccei-Quinn scale and axino mass in both DFSZ and KSVZ models, thereby offering a solution to the exclusion of higgsino-like WIMP scenarios by current direct detection limits.

CP-violation effects in neutral meson oscillations in the left-right weak interaction model

This paper demonstrates that the recently observed need for a right-handed vector boson admixture in neutron decay successfully explains CP-violation effects in neutral meson oscillations (K0K^0, D0D^0, B0B^0, and Bs0B_s^0) within an extended left-right weak interaction model, suggesting that the nature of CP violation is fundamentally linked to the presence of right-handed currents.
