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.

Bounds on the Tsallis Parameter from a deformed Neutrino Sector in the Early Universe

This paper generalizes neutrino energy density in the early universe using Tsallis nonextensive statistics and, by confronting the resulting deformation of the effective number of neutrinos with CMB, BAO, and BBN data, establishes stringent constraints on the Tsallis parameter qq such that ∣q−1∣|q-1| is limited to approximately 10−210^{-2} at 95% and 99% confidence levels.

Axion EFT in the BMHV Scheme: Flavor Currents, Evanescent Operators and Ward Identities

This paper presents a systematic two-loop analysis of axion effective field theory within the BMHV scheme, demonstrating how evanescent operators arising from the non-anticommuting nature of γ5\gamma_5 violate naive Ward identities and deriving the necessary finite renormalization to restore consistency and correctly recover the axial anomaly.

The connection between a classical vibrating drumhead and the masses of glueballs

This paper demonstrates that the mathematical equations governing the masses of glueballs in the holographic QCD hardwall model are identical to those describing the vibrations of a classical circular drumhead, thereby providing a compelling motivation for undergraduate students to study drumhead dynamics as a gateway to understanding advanced particle physics.

Layered dark structure with a Structuring Field: A Z4Z_4-symmetric Inert Doublet-Singlet realization and implications for the S8S_8 tension

This paper proposes the Layered Dark Sectors with a Structuring Field (LDS-SF) framework, realized via a Z4Z_4-symmetric Inert Doublet-Singlet Model, which introduces late-time scale-dependent suppression of structure growth to successfully alleviate the S8S_8 tension while remaining consistent with standard cosmological observations.
