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 presents a new Monte Carlo Glauber model for pA collisions utilizing KMR/SHRiMPS cross sections, demonstrating that their inherent impact parameter dependence and long-tailed wounded nucleon distributions effectively describe multiplicity distributions and enhance spatial anisotropy compared to other models.
This paper investigates two benchmark models featuring radiative tau mass generation that predict sizable anomalous magnetic moments and electric dipole moments for the tau lepton, with one model yielding particularly large EDM signals within the reach of future Belle II measurements.
This paper presents a novel high-twist analysis of form factors using two-pion distribution amplitudes, revealing that the significant cancellation between twist-2 and twist-3 contributions leads to a predicted decay rate far below experimental values, thereby challenging the single-meson interpretation of the and supporting an energy-dependent partonic structure for light scalar mesons.
This paper investigates the prospects for measuring -violation in decays at the LHC by introducing new time-dependent angular observables, demonstrating that future Run 3–5 datasets will enable their extraction with high precision and significantly enhance sensitivity to -violating short-distance effects and Wilson coefficients.
This paper presents state-of-the-art Standard Model predictions for production at the LHC's 13.6 TeV energy, providing updated cross sections and matched simulations in both five-flavour and four-flavour schemes while exploring their implications for Beyond-the-Standard-Model scenarios and Higgs coupling sensitivities.
Using 14 GeV-band gamma-ray burst photons within the Standard-Model Extension framework, this study employs Bayesian analysis to establish the most stringent constraints to date on isotropic, birefringence-free Lorentz-violating coefficients for dimensions and $10$, improving previous bounds by at least five orders of magnitude while indicating a preference for subluminal effects.
This paper introduces NeutrinoOsc3Flavor, a lightweight, NumPy-based Python framework that provides a transparent and pedagogical numerical solution for three-flavor neutrino oscillations in vacuum and matter, featuring exact CP phase dependence, cross-platform compatibility, and an independent analytical validation of matter effects using the Cardano method.
This paper demonstrates that longitudinal beam polarization at future colliders serves as a powerful control knob for quantum resources in fermion pair production, significantly modulating non-stabilizerness ("magic") while preserving entanglement and Bell nonlocality in -channel processes, and offering a unique experimental platform to observe these quantum information properties with high statistical significance.
This paper establishes a complete basis of dimension-eight operators in the SMEFT using Hilbert series formalism and demonstrates that their distinct kinematic signatures, specifically in right-handed neutrino pair production at the HL-LHC, can be experimentally distinguished from dimension-six effects using Boosted Decision Tree analysis.
This paper analytically solves the modified Dirac equation for Majorana neutrinos with transition magnetic moments in a magnetic field using a wave packet formalism to derive oscillation probabilities and demonstrate that decoherence effects, which depend on the relative strengths of vacuum and magnetic frequencies, can occur during propagation in supernova magnetic fields.
