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.
An analysis of global deep-inelastic scattering data reveals that nuclear modifications to nucleon structure functions remarkably cancel out in the valence quark region (), resulting in an isoscalar cross-section ratio near unity across all nuclei.
This paper presents a fully numerical study of parametric resonance in preheating, demonstrating that exact simulations reveal complex, coupling-dependent dynamics—such as mode-specific saturation and stochastic behavior—that differ significantly from traditional analytical approximations.
This paper evaluates various scalar field dark matter models against the rotation curve of the Andromeda galaxy (M31), finding that a two-component bulge baryonic structure combined with a smooth cored halo, such as Fuzzy Dark Matter, provides the most statistically consistent fit.
The paper proposes that the complex invariant mass spectrum observed in high-energy Pb-emulsion collisions can be explained as signatures of neutral color-singlet quark matter in both its deconfined and confined QED(U(1)) phases.
This paper reviews the QCD phase diagram at small chemical potentials, identifying three distinct regimes—the hadron gas, a "stringy fluid," and the quark-gluon plasma—which are differentiated by their symmetries, degrees of freedom, and scaling.
This paper utilizes Large-Momentum Effective Theory (LaMET) combined with first-principles functional QCD to calculate the kaon distribution amplitude, finding it to be single-peaked and asymmetric with specific values for its first and second moments.
The paper demonstrates that the Weyl (trace) anomaly induces a new non-dissipative vector current in accelerated relativistic fluids, uniquely determining the second-order transport coefficient that couples electromagnetic fields to fluid acceleration.
This study demonstrates that searching for resonant Higgs boson production via the process at the FCC-ee can achieve a 95% confidence level upper limit on the electron Yukawa coupling modifier of , providing the most stringent constraint to date in simulation-based studies.
This paper proposes a new classification for scalar mesons and identifies as a primary glueball candidate, utilizing a topological soliton framework to model glueball energy spectra and internal structures in agreement with lattice QCD and experimental data.
This paper investigates the potential of heavy neutral leptons (HNLs) to mediate lepton-number-violating -meson decays, demonstrating that meson channels offer significantly enhanced sensitivity for detecting these physics beyond the Standard Model effects compared to other modes.
