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.
This paper investigates sub-GeV dark matter signatures from dark showers in strongly-interacting dark sectors, demonstrating that beam-dump experiments like SHiP could detect multiple displaced vertices in single events to reveal the dark sector's structure, while also evaluating current constraints from NA62 and BaBar and future sensitivities at Belle II.
This paper proposes a novel framework where interactions between a rotating QCD axion and dark magnetic monopoles simultaneously generate the observed baryon asymmetry and deplete the axion's kinetic energy to match the dark matter density, requiring an axion decay constant below GeV.
This paper resolves unphysical divergences in two-loop renormalization group functions within on-shell effective field theory bases by demonstrating that including omitted non-minimal source terms restores renormalizability and renders the RG functions finite, with remaining ambiguities restricted to unphysical flavor rotations.
This paper proposes a two-component dark matter model within an SU(2) dark sector stabilized by a residual symmetry and coupled to the Standard Model via a Higgs portal, demonstrating viable parameter spaces that satisfy theoretical consistency and a comprehensive set of experimental constraints.
This paper presents a model-independent analysis of HERA's exclusive coherent diffractive production data using artificial neural networks to predict differential cross-sections and extract a - and -dependent exponential slope by integrating HERA and LHC datasets.
This paper proposes that heavy right-handed neutrinos in the type-I seesaw framework can generate the necessary bias to annihilate domain walls formed by discrete symmetry breaking, thereby producing a stochastic gravitational wave signal with correlated features that link the seesaw scale to observable GW and CMB data while simultaneously enabling resonant leptogenesis to explain the universe's baryon asymmetry.
This study presents the first systematic analysis of rigidly rotating protoquark stars within the density-dependent quark mass framework, revealing that thermal evolution and rapid rotation significantly enhance stellar stability and deformation, thereby creating distinct observational signatures that future multimessenger data must account for to robustly identify quark matter in compact stars.
This paper presents the first fully differential predictions for Higgs-boson pair production via gluon-gluon fusion at NLO in the heavy-top limit, demonstrating a threefold reduction in scale uncertainties and incorporating top-quark mass effects to provide highly precise theoretical benchmarks for LHC searches.
The paper introduces CaloTrilogy, a unified framework that achieves high-quality, physics-guided particle shower generation for modern calorimeters in just one or a few inference steps by combining an average velocity field integrator, a data-derived generative prior, and training-time physics constraints, thereby overcoming the computational inefficiencies of existing flow and diffusion models.
This paper presents a new implementation of baryon asymmetry calculations in the BSMPT code based on a generalized WKB ansatz for transport equations, which is validated and applied to the CP-violating 2-Higgs-Doublet Model to analyze key dependencies, uncertainties, and the interplay with gravitational wave signals.
