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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper investigates how the chameleon mechanism in scalar-tensor theories causes superradiant scalar clouds around Kerr black holes to exhibit unique growth and stimulated decay patterns in non-uniform matter distributions, generating distinct electromagnetic signals that can differentiate fundamental scalars from other light bosonic fields.
This paper investigates the pair production of charged scalars () within the scotogenic model, demonstrating that the process is dominated by -channel exchange of singlet right-handed fermions (including the dark matter candidate) and providing predictions for future high-energy colliders to test the model's parameter space.
This paper analyzes the transition form factors using newly derived light-cone distribution amplitudes within the light-cone sum rule framework, demonstrating that intrinsic charm and gluonic components significantly influence the observables, particularly stabilizing the channel while enhancing the sensitivity of the channel at high .
This paper presents a detailed calculation of the 2-loop self-energy for a scalar particle using a simple sector decomposition method to efficiently separate ultraviolet divergences from finite parts, enabling both analytic and numerical renormalization.
This paper establishes a quantitative framework demonstrating that ultra-peripheral heavy-ion collisions via Drell-Söding pion-pair production generate interference-induced entanglement, which manifests as a measurable second-harmonic azimuthal asymmetry in momentum space, thereby offering a robust experimental signature of quantum coherence in relativistic environments.
The paper proposes GALILEO, a novel experimental method using a high-precision resonant Michelson interferometer to detect light dark matter by measuring the oscillation-induced changes in the refractive index of electro-optical materials, thereby exploring a previously uncharted mass range beyond the capabilities of traditional microwave cavity haloscopes.
This paper investigates how the differential Galactic acceleration of double white dwarf binaries affects their gravitational wave frequency chirps as observed by LISA, demonstrating how these measurements can be used to refine parameter estimation and map the distribution of matter in the Milky Way.
This paper proposes using Noether's second theorem, rather than the first, to derive unique and physically consistent energy-momentum and spin currents for free massive Dirac particles, thereby resolving the ambiguities typically associated with pseudogauge transformations in relativistic spin hydrodynamics.
This paper utilizes recent LHCb and Belle II measurements of CP asymmetries in decays, combined with flavor-SU(3) relations and first-order breaking corrections, to generate new Standard Model predictions for CP violation and decay rates in related and processes.
This paper investigates lepton-flavor violation in electron-muon nuclear conversion and rare radiative meson decays induced by a sub-GeV dark photon, providing estimates for current and future fixed-target experiments and applying these findings to analyze the specific decay channels .
