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 utilizes a constituent quark equal-velocity combination model to demonstrate that the transverse momentum dependence of the ratio in high-energy collisions is governed by the discrete curvature of the strange quark spectrum just before hadronization, a feature attributed to strong collective flow in the partonic stage.
This paper presents a causal and stable first-order relativistic BDNK magnetohydrodynamic framework in a boost-invariant background, revealing that magnetic fields respond strongly to temperature evolution while their feedback remains subleading, ultimately leading to a suppression of the low-mass dilepton spectrum due to enhanced cooling.
This paper presents a numerical solution for boost-invariant, cylindrically symmetric perfect spin hydrodynamics with wounded nucleon initial conditions, revealing a unique coupling between azimuthal and longitudinal spin polarization components that induces total polarization via the longitudinal magnetic and azimuthal electric fields.
This paper investigates the radiative decay within nonrelativistic effective field theory, predicting a branching fraction of dominated by meson loops and suggesting this channel as a promising avenue for discovering the molecular state .
This paper proposes that in quadratic gravity, the massive ghost responsible for unitarity violation is confined within zero-norm states via a BRST quartet mechanism involving a bound state with Faddeev-Popov ghosts, thereby restoring unitarity in a manner analogous to color confinement in QCD.
This paper demonstrates that by employing a realistic magnetar magnetic field profile, the IXPE and eXTP missions can quantitatively detect vacuum birefringence, with 1RXS J170849.0-400910 identified as the optimal candidate due to a predicted time delay significantly larger than previous estimates.
This review article outlines the theoretical foundations of magnetic monopoles and provides a historical overview of experimental searches, with a specific focus on current efforts in cosmic and collider experiments, particularly at the Large Hadron Collider.
This paper investigates Collins azimuthal asymmetries in pion-in-jet production within polarized lepton-proton collisions at the Electron-Ion Collider using a simplified TMD approach, demonstrating that these processes offer a theoretically cleaner and more direct probe of the transversity distribution and its sea-quark components compared to polarized proton-proton scattering, thereby providing a crucial test for the universality of the Collins function and TMD factorization.
This paper presents the first complete two-loop calculation of the electron electric dipole moment and lepton-flavor violating decay rates within the unconstrained two-Higgs doublet model, incorporating general Yukawa interactions and Higgs potential phases, with results made available through a public Python implementation.
This paper theoretically extends the Lifshitz formula to demonstrate that the anomalous magnetic moment of Dirac fermions significantly enhances the fermionic Casimir energy under magnetic fields, particularly through the gapless behavior of the lowest Landau level, while providing quantitative estimates for electrons, muons, and constituent quarks.
