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 the cosmological signatures of late-time quantum vacuum decay, demonstrating that precision distance measurements and CMB anisotropy data can constrain or detect transitions that alter vacuum energy and convert dark matter, with specific models offering a potential resolution to tensions within the standard CDM framework.
This paper presents the first calculation of the twist-3 gluon contribution to the Sivers asymmetry in production via semi-inclusive deep inelastic scattering, demonstrating that this observable is ideal for constraining the -even twist-3 gluon distribution and providing numerical predictions for future electron-ion collider experiments.
This paper presents the design of CONDOR, a proposed high-altitude gamma-ray and cosmic-ray observatory located at 5300 meters in the Atacama Desert, which utilizes a modular array of 6000 plastic scintillator panels to achieve a 100 GeV energy threshold and enable continuous all-sky monitoring for multimessenger astronomy from the Southern Hemisphere.
This paper presents projected 95% confidence level limits on Axion-Like Particle couplings from future collider data, integrating these with constraints from the muon anomaly, thermal dark matter relic density, and Higgs signal strengths to define the viable parameter space for ALPs even in the absence of a significant muon deviation.
This paper proposes a cascade decaying dark matter model that incorporates both early- and late-time modifications to CDM, finding that while it can yield a higher value, it ultimately fails to reduce the Hubble tension below the level, thereby revising previous claims in the literature.
This paper proposes and validates an empirical precision extrapolation method to achieve high-precision -gauge fixing in lattice QCD, successfully reproducing -dependent renormalization constants for local quark bilinear operators up to with 0.3% accuracy.
This paper introduces the petrifyML package, a tool designed to ensure the stable preservation and future reproducibility of high-energy physics machine learning algorithms by converting their configurations into industry-standard ONNX format or native Python and C++ code.
This study refines the classical Greisen profile by introducing a zenith-angle-dependent empirical correction to the shower age parameter, demonstrating that the modified model reduces deviations in particle number predictions for low-energy (20–800 GeV) cosmic gamma-ray showers to below 4.7% compared to CORSIKA simulations, thereby offering a more accurate and computationally efficient tool for high-altitude observatories like HAWC and CONDOR.
This paper demonstrates that in both Loop Quantum Cosmology and its modified variant, a combined potential featuring an ekpyrotic component can effectively suppress shear during the bounce to resolve anisotropy issues, while subsequently allowing the inflationary component to dominate and produce a sufficiently long inflationary phase.
This paper characterizes the coherent and stochastic signals produced by ultralight dark matter with quadratic couplings in pulsar timing arrays, finding that while current PTA observations can compete with other probes for coherent signals, they remain less sensitive than equivalence principle tests for stochastic signals.
