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 nucleon energy correlators as a novel, inclusive framework using azimuthal asymmetries in the target fragmentation region to linearly constrain electroweak light-quark dipole operators at the Electron-Ion Collider without requiring polarized beams or final-state hadron identification.
This paper derives master formulas and numerous -spin sum rules for two-body bottom baryon decays by introducing a new operator to handle mixed transitions, providing predictions for branching fractions, testing flavor symmetry beyond the symmetry limit, and establishing asymmetry relations for the first time.
This paper proposes a general parametrization for new physics corrections to gauge couplings, demonstrating that full unification typically occurs near the Standard Model's partial unification scale unless corrections are highly asymmetric, while also revealing a phenomenologically significant possibility for unification at approximately 100 TeV via string-inspired corrections.
This paper presents a phenomenological study demonstrating that the Large Hadron Collider can probe supersymmetric DFSZ axion models with higgsino masses below 1 TeV and axion decay constants under GeV by analyzing displaced decays of neutralinos into axinos using Monte Carlo simulations and detector sensitivity estimates.
This paper derives general formulas for reconstructing the flavor fractions of astrophysical neutrinos at their sources from observed data, revealing an inherent divergence in distinguishing and flavors due to - interchange symmetry in the lepton mixing matrix and demonstrating that only specific combinations of flavor fractions can be precisely extracted under exact symmetry conditions.
This paper proposes a quark-meson framework incorporating temperature-dependent quark masses and anomalous magnetic moments to reconcile lattice QCD magnetic susceptibility data with theoretical models, demonstrating that quark degrees of freedom must emerge significantly below the QCD cross-over temperature (around 120 MeV) to explain the observed paramagnetism.
This paper demonstrates that the CERN SHiP experiment can probe sequential freeze-in dark matter mediated by dark photons with masses between and $10$ GeV, predicting a specific dark charge and a narrow mixing parameter range () that survives current constraints while remaining testable via proton bremsstrahlung signals.
This paper investigates a relativistic self-gravitating equilibrium system with slow steady flow by developing a perturbative framework to derive differential equations for structural corrections and proposing a new condition that uniquely determines the unconventional form of the entropy current and its leading-order parameter.
This paper demonstrates that while naive extrapolations of microphysical absorption rates suggest ultralight bosons could rapidly drain neutron star rotational energy via superradiance, accounting for collective multiple-scattering effects in dense nuclear matter significantly suppresses these rates, thereby reconciling stellar cooling constraints with superradiance stability.
This paper demonstrates that the VCDM framework of minimally modified gravity, when combined with current cosmological data and an extended neutrino sector, robustly accommodates neutrino constraints while predicting a stable late-time dark energy transition that significantly alleviates the tension.
