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.

Momentum and Matter Matter for Axion Dark Matter Matters on Earth

This paper investigates how Earth's matter effects and the finite momentum of axion dark matter influence experimental searches, finding that while canonical axion models remain largely unaffected, lighter axions with stronger couplings may experience reduced field values but enhanced spatial gradients, significantly altering detection sensitivity.

Dark, deep, deconfining: Phase transitions in neutron stars as powerful probes of hidden sectors

This paper proposes that interactions between hidden sector particles and neutron star nucleons can overcome energy barriers to trigger deconfinement phase transitions, potentially converting neutron stars into black holes or gamma-ray bursts, thereby allowing the observed existence of ancient neutron stars to set constraints on dark matter interactions and nucleon decay lifetimes that are orders of magnitude stricter than terrestrial limits.

On the Energy Distribution of the Galactic Center Excess' Sources

By employing a neural network simulation-based inference approach to jointly analyze spatial and spectral data, this study demonstrates that the Galactic Center Excess is consistent with a diffuse dark matter signal or an exceptionally large population of dim point sources, challenging earlier conclusions that favored a smaller number of brighter sources.

Explaining 650 GeV and 95 GeV Anomalies in the 2-Higgs Doublet Model Type-I

This paper proposes a 2-Higgs Doublet Model Type-I framework with a softly broken Z2\mathcal{Z}_2 symmetry to simultaneously explain the 650 GeV γγbbˉ\gamma\gamma b\bar b excess at the LHC and the 95 GeV anomalies in bbˉb\bar b, γγ\gamma\gamma, and τ+τ\tau^+\tau^- channels from LEP and LHC data through the production of a 650 GeV pseudoscalar decaying into a 125 GeV Higgs and a Z boson, alongside a 95 GeV scalar state, achieving a combined significance of 2.5σ2.5\sigma.

Effect of Moduli Redefinitions on Fibre Inflation

This paper proposes a novel fibre inflation model within the perturbative large volume scenario that utilizes base modulus redefinitions and various string corrections to achieve inflationary parameters consistent with ACT data while simultaneously incorporating a quintessence sector to explain both early- and late-time cosmic acceleration.

Generalized relativistic second order magnetohydrodynamics: A correlation function approach using Zubarev's nonequilibrium statistical operator

This paper constructs a generalized second-order relativistic magnetohydrodynamics framework using Zubarev's nonequilibrium statistical operator to derive all dissipative tensors and Kubo formulas for a parity- and charge-conjugation-symmetric magnetized plasma, while extending the formalism to include nonlocal contributions.

Universal geometric framework for black hole phase transitions: from multivaluedness to classification

This paper establishes a universal geometric framework linking the synchronized multivaluedness observed in black hole phase transitions to a three-sheeted covering structure arising from two non-degenerate critical points in the temperature function, thereby providing a rigorous classification scheme and a unified perspective on black hole thermodynamics and dynamics.
