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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes the DARK-ROSE experiment, which utilizes high-quality-factor millimeter-sized spherical dielectric resonators to enhance axion-mediated photon-to-photon transitions by tailoring Mie resonances to match expected axion frequencies, thereby offering a new pathway to detect axion dark matter.
This paper proposes a new mechanism where cosmic rays scattering with supernova neutrinos in dense astrophysical environments produce a detectable flux of high-energy boosted neutrinos, offering a novel method to constrain ultra-high energy proton-neutrino cross sections through both Standard Model predictions and potential new physics enhancements.
This paper introduces a fast, differentiable normalizing-flow surrogate trained on ALICE data to precisely constrain femtoscopic source models, thereby reducing the dominant uncertainties in light antinuclei coalescence parameters ( and ) from orders of magnitude to the few-percent level and significantly improving predictions for cosmic-ray dark matter signatures.
This paper provides an overview of how machine learning-based simulation-based inference methods can be applied within both Bayesian and frequentist frameworks to solve inverse problems, while also addressing their use in Empirical Bayes and unfolding tasks, along with validation strategies and inherent limitations.
This paper presents the first experimental exclusion limits on the agnostic neutrino Standard Model Effective Field Theory (SMEFT) parameter space by recasting a CMS search for heavy Majorana neutrinos in the same-sign dimuon plus two jets channel, constraining effective coupling strengths for heavy-neutrino masses between 200 GeV and 15 TeV.
This paper investigates ALP pair production at the LHC, demonstrating that the four-photon signature from the non-resonant process can significantly constrain the multidimensional parameter space of dimension-5 and dimension-6 ALP interactions, while also reinterpreting ATLAS Higgs-resonant search results to reveal complex, non-trivial constraints.
This paper improves the analysis of quark confinement in the proton by incorporating light-cone QCD sum rules and formulating the quark force reconstruction as a regularized inverse problem, yielding a less model-dependent determination that remains consistent with a linear QCD potential.
This paper revisits and refines the exclusion limits on a long-lived vector boson from the SLAC E141 experiment by performing a dedicated reanalysis with improved modeling of the experimental setup, thereby providing a more accurate assessment of the tension between these constraints and the ATOMKI anomaly.
This paper demonstrates that combining the high-statistics measurements from the T2HK experiment with the second-oscillation-maximum configuration of ESSnuSB effectively resolves parameter degeneracies between Lorentz-violating effects and standard oscillation parameters, thereby enabling precise constraints on Planck-scale Lorentz Invariance Violation.
This paper demonstrates that rainbow cosmology, through energy-dependent modifications to the Friedmann equation and scalar field dynamics, provides a viable dynamical mechanism for generating the observed baryon asymmetry during the radiation-dominated era without requiring supersymmetry.
