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 proposes a pseudo-Dirac fermion dark matter model with a vector mediator and freeze-in production via low reheating temperatures to explain the high-energy nuclear recoil event observed by the LUX-ZEPLIN experiment, demonstrating how this framework allows for a continuous parameter space that decouples the dark matter mass from the direct-detection cross section.
This paper introduces PDG2021+, an updated and transport-ready hadron list based on the 2021 Particle Data Booklet for heavy-ion collision simulations, and validates its impact on key observables like the pion mean transverse momentum while quantifying systematic uncertainties arising from decay modeling approximations.
This paper proposes a microscopic model of the dark sector based on Hot New Early Dark Energy (Hot NEDE) and spontaneous symmetry breaking, which introduces a dark radiation matter decoupling mechanism to resolve the Hubble tension by aligning cosmological data with the SH0ES determination at a 1.4 level.
This paper proposes a novel mechanism where inflaton quanta are regenerated from the thermal bath after reheating, offering a new probe for reheating dynamics and a potential explanation for the observed dark matter abundance.
This paper demonstrates that the proper time renormalization group flow, despite not being an exact functional equation, correctly reproduces the universal one- and two-loop -function coefficients and anomalous dimensions for both scalar and Yang-Mills theories, thereby validating its reliability for capturing essential renormalization content across diverse physical applications.
This paper investigates the relativistic 3D weak-neutral axial-vector and spin distributions in nucleons, demonstrating that the conventional axial radius is physically meaningless while defining a genuine 3D spin radius dependent on the induced pseudoscalar form factor, and provides corresponding cross-section formulas to guide future neutrino-scattering experiments.
This paper proposes that dark acoustic oscillations (DAO) occurring in the early Universe can bias the interpretation of DESI DR2 data, offering an alternative to evolving dark energy that reconciles the observed phantom crossing with Planck and supernova data while potentially resolving the Hubble tension.
This paper presents a model-independent global fit of top-quark flavour-changing neutral current interactions within the SMEFT framework, deriving stringent constraints on complex couplings and Wilson coefficients by combining diverse experimental data while providing predictions for rare branching ratios and CP asymmetries.
This study demonstrates that the Early Dark Energy model, when constrained by a combination of Planck, ACT, SPT, DESI, and JWST data, successfully resolves the Hubble tension to the level while providing a statistically superior fit to observations compared to the standard CDM model.
This paper proposes an anomaly-free model featuring an inelastic scalar dark matter candidate that explains the LUX-ZEPLIN nuclear-recoil event while evading stringent solar-neutrino constraints due to suppressed solar capture and nonthermal stalling of the signal within the Sun.
