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 in the vector portal model, a dark magnetic field generated within the Sun can act as a barrier that deflects low-mass dark matter particles, thereby suppressing the high-energy solar-reflected dark matter flux and necessitating a revision of detection sensitivity for ground-based experiments.
This paper demonstrates that the upcoming MUonE experiment, leveraging its high-resolution tracking and unique geometry to detect displaced decays of vector bosons produced in muon-electron or muon-nucleus scattering, can uniquely probe and fill a long-standing gap in the parameter space for light vector boson mediators with masses up to approximately 100 MeV.
This paper investigates the High-Luminosity LHC's sensitivity to new invisible scalars and fermions with masses below 50 GeV via semi-visible Higgs decays within the dark-SMEFT framework, utilizing both cut-based and multivariate analysis techniques to distinguish operator structures and benchmark results against invisible Z-width constraints and perturbative unitarity.
Using a unified framework to analyze combined data from LZ, PandaX-4T, and XENONnT, this study suggests that velocity-dependent or inelastic dark matter interactions could explain high-energy nuclear-recoil-like events with up to 3.5σ significance, though these findings are highly sensitive to uncertainties in Xe double electron capture backgrounds.
This paper proposes that a modified post-inflationary expansion history can simultaneously suppress the tensor-to-scalar ratio and render relic gravitons invisible in the aHz range while allowing for a potentially detectable high-frequency signal and satisfying constraints from large-scale magnetism.
This paper investigates the electromagnetic properties of fully charm tetraquarks by deriving analytical expressions for significant next-to-leading-order QCD corrections to their two-photon decay amplitudes and providing theoretical predictions for their production cross sections in ultra-peripheral and electron-positron collisions.
This paper proposes a extended Standard Model where radiative Dirac neutrino masses and dark matter stability are linked via a residual symmetry, demonstrating that the resulting dark matter candidates satisfy observational constraints and offer promising detection prospects at current and future colliders.
This paper corrects a sign error in the convention dictionary used by Arroyo-Ureña et al. to derive structure-dependent amplitudes from Guo and Roig's work, thereby confirming the relative sign between vector and axial sectors while demonstrating that the resulting numerical impact on radiative corrections remains negligible.
This paper proposes a minimal high-quality QCD axion model where the Peccei-Quinn symmetry arises as a gauge-origin boundary remnant of five-dimensional invariance, allowing the axion to be a Wilson-line phase that retains exponential quality protection without requiring bulk QCD, warping, or color Chern-Simons terms.
This paper proposes using high-energy photons that convert into electron-positron pairs within the Belle-II detector at lepton colliders to measure quantum information observables, demonstrating that single and double conversion processes can significantly probe phenomena such as Bell inequality violations, quantum discord, and steerability in GeV-scale diphoton systems.
