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 robust likelihood ratio framework designed to evaluate the compatibility of highly motivated theoretical models with experimental residuals, specifically addressing the challenge of detecting subtle new physics signals that manifest as small deviations from established background predictions.
This paper introduces a model-independent framework using public Belle II data to reinterpret the decay channel, establishing it as a dual probe for new physics that yields the strongest current limit on the branching fraction and constrains axion-quark couplings.
This paper proposes a lepton parity-protected dark matter candidate produced via freeze-in mechanisms that yields observable signatures in the effective number of relativistic species () and gravitational waves, offering complementary probes for future cosmological experiments.
This paper identifies a previously overlooked Wess–Zumino–Witten structure within the hidden-local-symmetry formulation of vector mesons that leads to the topological quantization of their anomalous couplings, thereby explaining the success of vector-meson dominance and offering a testable distinction between gauge and matter-field descriptions through precision measurements of form factors.
This paper demonstrates that while the Minimal Flavor Violation framework with a single dark matter multiplet can naturally explain either the or excess observed at Belle II and NA62, it cannot simultaneously account for both anomalies, thereby highlighting the specific constraints and testability of flavored dark matter models.
This paper introduces a Physics-Informed Neural Network framework using a "Teacher–Student" strategy to extract a model-independent color dipole amplitude from HERA data, which successfully predicts exclusive photoproduction cross-sections without parameter retuning, thereby providing strong evidence for the process-independence of the gluon saturation scale in high-energy QCD.
This paper provides a comprehensive, multi-method analysis (perturbative, semiclassical large-, and integrability) of the Gross-Neveu model, demonstrating that at large chemical potential, the system enters a consistent crystalline phase characterized by the condensation of bound states and the emergence of two new dynamically generated scales that govern nonperturbative effects and the oscillatory chiral condensate.
This paper demonstrates that various unitarization prescriptions for the Sommerfeld enhancement in self-interacting dark matter are effectively equivalent and regulator-independent, leading to a unified, regulator-free formula for multi-state systems expressed in terms of the standard enhancement factor, the hard annihilation amplitude, and the scattering -matrix.
Using the 15-year NANOGrav data, this work constrains inflationary parameters and the reheating phase, finds a preference for a blue-tilted tensor spectrum and a radiation-like reheating phase, simultaneously demonstrates that observations favor a specific non-Bunch-Davies alpha-vacuum, and suggests that frequency-dependent modifications of this vacuum could resolve the blue-tilt problem.
This paper derives both electric and magnetic Carrollian fermion actions from a single Bargmann-invariant Dirac action via null reduction, demonstrating how the decomposition of Dirac spinors into dynamical ("good") and constrained ("bad") light-cone modes in the parent theory naturally yields the respective magnetic and electric sectors upon deformation to Carroll spacetime.
