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.

Gravothermal Collapse: Robust Against Baryonic Feedback

Using N-body simulations and a semi-analytical model, this study demonstrates that gravothermal collapse in self-interacting dark matter halos remains robust against baryonic feedback, with high-concentration halos collapsing despite strong feedback and median-concentration halos resuming collapse after feedback ceases, thereby supporting the identification of dense compact perturbers in strong-lensing observations as core-collapsed SIDM halos.

Signals of New Resonances from Di-Lepton Non-Universality in the Bottomonium Mass Region at the Large Hadron Collider

This paper classifies new physics models featuring narrow boson resonances that could induce significant di-lepton non-universality in the bottomonium mass region at the LHC through enhanced di-tau decays, proposing that simultaneous measurements of di-electron, di-muon, and di-tau spectra could reveal these new states or non-Standard Model bottomonium decays.

CJ26 Global QCD Analysis with Large-xx Jefferson Lab 6 and 12 GeV Data

The CJ26 global QCD analysis presents a new set of NLO parton distribution functions by incorporating the complete suite of JLab 6 GeV and the first published 12 GeV data to uniquely disentangle higher-twist effects from off-shell nucleon corrections, thereby significantly reducing uncertainties in the large-xx n/pn/p structure function and d/ud/u valence quark ratios.

Accessing Exotic Hadronic States via Charmed-Meson Femtoscopy in Relativistic Heavy-Ion Collisions

This paper demonstrates that relativistic heavy-ion collisions, simulated via the PHSD transport approach and CATS correlation analysis, provide a superior environment compared to proton-proton collisions for studying charmed-meson interactions and probing exotic hadronic states through femtoscopic correlations due to enhanced charm production, reduced relative momenta, and suppressed initial-state effects.

Deeply bound dibaryon d∗(2380)d^*(2380) from meson-exchange saturation ΔΔ\Delta\Delta effective field theory

This paper proposes an RG-improved effective field theory framework that reorganizes short-range dynamics by integrating out meson-exchange degrees of freedom, successfully describing the deeply bound d∗(2380)d^*(2380) dibaryon as a ΔΔ\Delta\Delta bound state with a binding energy consistent with experimental data and large-NcN_c expectations.

Sensitivity of jet quenching to the initial state in heavy-ion collisions

By employing resummation schemes to derive analytical rates for radiative energy loss in evolving backgrounds, this paper demonstrates that strong jet quenching requires a medium equilibration time longer than its mean free path and reveals that initial-state evolution with weak jet coupling typically enhances azimuthal asymmetry for a given suppression factor.

Anomalous Dimension of a General Effective Gauge Theory I: Bosonic Sector

This paper classifies physical operators up to dimension six in the most general bosonic effective gauge theory and computes their complete one-loop anomalous dimensions using on-shell and geometric techniques, providing a universal framework that is validated against and extends existing results for the Standard Model Effective Field Theory and axion-like particle models.

Gravitational Wave Signatures of U(1)X\mathrm{U(1)_X} Breaking and Right-Handed Neutrino Dynamics

This paper investigates a minimal extension of the Standard Model with a local U(1)XU(1)_X gauge symmetry and right-handed neutrinos, demonstrating that the resulting first-order phase transition produces a stochastic gravitational wave spectrum detectable by future experiments while simultaneously explaining neutrino masses and baryogenesis through thermal leptogenesis.
