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.
The paper proposes that the single high-energy nuclear recoil event observed by LUX-ZEPLIN can be explained by inelastic dark matter scattering near the kinematic limit, which predicts a distinctive seasonal signal that vanishes for part of the year and will be testable by future experiments with larger target masses.
This paper proposes that the isolated high-energy nuclear recoil event observed by the LUX-ZEPLIN experiment can be explained by the up-scattering of atmospheric neutrinos into a massive beyond-Standard-Model particle, offering a viable alternative to galactic dark matter interpretations.
This study investigates the molecular nature of and by calculating their strong decay widths, concluding that while is likely a molecule, may not be, and subsequently predicting the existence of their heavy-quark symmetry partners in the charm sector and as higher-spin states to guide future experimental searches.
This paper proposes and evaluates a complementary missing-energy search strategy for the Light Dark Matter eXperiment (LDMX) by utilizing its Electromagnetic Calorimeter as an active target, demonstrating sensitivity to previously unexplored light dark matter parameter spaces with effective interaction strengths as low as for 1 MeV dark matter candidates.
This paper proposes and demonstrates that high-intensity muon beams can enable a Muonium-based Axion Search (MASH) using resonant quantum transitions to constrain axion-muon couplings in the 18–130 eV mass range, thereby offering a new spectroscopic channel that complements and tightens limits beyond existing muon measurements.
This paper presents a high-precision lattice QCD calculation of the hadronic contributions to the running of the electromagnetic coupling and the electroweak mixing angle, revealing significant tensions with data-driven estimates at intermediate energy scales while providing a more precise determination of the coupling at the Z-pole that slightly deviates from global electroweak fit predictions.
This paper presents a high-precision first-principles calculation of the hadronic running of electroweak gauge couplings using lattice QCD and the Euclidean split technique, achieving a determination of the electromagnetic coupling at the Z-boson mass scale that is more than twice as precise as recent phenomenological estimates and reveals a significant deviation from -based results at low energy.
This paper critiques a recent study on quantum resources in polarized hyperon–antihyperon systems, arguing that its interpretation of hadronization as a correlated dephasing channel with memory lacks physical justification and that its claims of non-Markovianity and resource protection are merely phenomenological artifacts rather than established physical effects.
This paper proposes a model where an exact gauge symmetry, emerging from a lepton-flavor non-universal framework, simultaneously ensures exact proton stability, generates realistic neutrino masses, and provides a high-quality QCD axion dark matter candidate by suppressing PQ-violating operators to sufficiently high dimensions.
This paper uses SN1987A neutrino data to constrain neutrino-dark-fermion interactions mediated by a light scalar, demonstrating that current limits are highly sensitive to emission models and flavor conversion but can be robustly restored by future high-statistics observations from Hyper-Kamiokande.
