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 establishes a comprehensive framework for perturbative unitarity bounds in models featuring extra doublet, neutral singlet, and charged singlet scalars by proposing a minimal set of scattering matrices and providing a public Mathematica tool, BounDS, to implement and verify these constraints.
The paper conjectures a remarkable correlation among the first-row elements of the lepton mixing matrix, , which remains consistent with unitarity limits and is currently supported by JUNO and Daya Bay precision measurements at nearly the confidence level.
This paper proposes that the unexpected survival of very-high-energy gamma rays from GRB 221009A can be explained by a combined scenario of photon-axion-like particle oscillations and subluminal quadratic Lorentz invariance violation, which together enhance photon transparency more effectively than either mechanism alone.
Motivated by the upcoming Super Tau-Charm Facility, this paper demonstrates that axion-like couplings can induce a complex electric dipole moment with both real and imaginary components that are within the projected sensitivity reach of future experiments at Belle II and the STCF, thereby imposing new constraints on GeV-scale physics.
This paper demonstrates that while Fermi degeneracy pressure stabilizes self-gravitating systems in Newtonian gravity, general relativity can render such systems unstable even at low temperatures, potentially driving the gravothermal collapse of dark matter into massive black holes in the early Universe.
This paper estimates the signal for large extra dimensions and the corresponding next-to-leading order BFKL QCD background for high-mass dijet production with large rapidity separation to assess the discovery potential at the HL-LHC and future colliders.
This paper presents an extension of the MadGraph5_aMC@NLO framework that enables automated leading-order calculations for S-wave quarkonium and leptonium production within NRQCD and NRQED formalisms, offering seamless integration with Beyond the Standard Model scenarios and highlighting the necessity of careful theoretical analysis beyond simple velocity-scaling rules.
This paper proposes and analyzes a theoretical framework for producing and detecting light fermionic dark states with millicharge or electromagnetic form factors using a 100 MeV electron beam and CCD sensors, potentially opening a new window to probe unconstrained parameter spaces for such particles.
This paper presents a high-precision lattice QCD determination of the nucleon iso-vector scalar and tensor charges at the physical point by employing a novel "blending" method to suppress excited state contamination across 15 ensembles, yielding the most accurate predictions to date with comprehensive systematic error analysis.
This study systematically investigates the gravitational wave emission from a population of millisecond pulsars proposed to explain the Galactic Center GeV gamma-ray excess, concluding that while current detectors cannot observe them, next-generation instruments like the Einstein Telescope and Cosmic Explorer may detect these signals to definitively test the pulsar versus dark matter interpretations of the excess.
