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 demonstrates that F-theory Grand Unified Theories impose a strict upper bound on the coupling-to-mass ratio of axion-like particles, predicting that no such particle can exist significantly above the QCD axion band in controlled regimes, thereby rendering these theories falsifiable by the discovery of axion-induced cosmic birefringence or similar phenomena.
The paper proposes that the FCC-ee can probe lepton number violation and test neutrino mass ordering through high-multiplicity final-state signatures like , which are enabled by the minimal linear seesaw mechanism to avoid suppression by small neutrino masses and yield over 1,000 expected events with negligible Standard Model background.
This paper presents an extended analysis of pseudo-scalar dark energy models, demonstrating that while axion-like potentials require large anomaly coefficients to be viable, scenarios with quadratic, linear, or Ratra-Peebles potentials can successfully explain both dark energy and cosmic birefringence with a symmetry-breaking scale near the GUT scale.
This paper demonstrates that the lower energy thresholds of Super-Kamiokande and the future Hyper-Kamiokande water Cherenkov detectors enable them to constrain previously unexplored parameter space for lighter millicharged dark matter in the Sun, offering sensitivity to fractional abundances nearly an order of magnitude below current IceCube limits.
This paper challenges the common assumption that large occupation numbers alone justify a classical field description for identical bosons, demonstrating instead that the validity of such a description depends critically on the quantum state's proximity to a coherent state rather than merely on the magnitude of the occupation number.
This paper extends the baryo-charmonium model to the doubly-strange sector to predict a distinct pattern of negative-parity hidden-charm pentaquarks, characterized by a near-degenerate doublet of kaon-associated states and masses consistent with recent molecular and QCD sum-rule calculations.
This paper proposes that precise measurements of total charm production in heavy-ion collisions, when combined with improved calculations of initial hard scatterings, can serve as a signature to infer properties of the pre-equilibrium stage, despite current theoretical uncertainties.
This paper presents a general framework for subtracting nonflow effects from multi-particle cumulants in small collision systems by leveraging scaling and dipolar flow estimators, thereby enabling the systematic quantification of collective flow at particle multiplicities previously inaccessible due to uncontrolled nonflow residuals.
This paper employs a relativistic constituent quark model with the Faddeev approach to investigate how medium-induced variations in constituent quark masses and couplings affect the light and strange baryon spectrum, finding that mass shifts significantly alter ideal-gas baryon yields and ratios, particularly when baryons exhibit different constituent-quark-mass dependencies.
This paper investigates the formation of light nuclei and hypernuclei in Au+Au collisions at using a parameter-free coalescence framework based on realistic -body wave functions, revealing species-dependent formation times and improving the description of yields through additional cluster-nucleon channels while providing predictions for heavier hypernuclei.
