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 predicts that future electron-ion collider experiments at high inelasticity will observe an enhancement in the ratio of nuclear reduced cross-sections due to saturation effects, a phenomenon distinct from standard parton distribution ratios that highlights the critical role of the nuclear longitudinal structure function and offers a method to quantify gluon shadowing.
This paper investigates higher-twist corrections to reduced cross-section ratios at the Electron-Ion Collider (EIC) using a color dipole model, demonstrating that including twist-4, -6, and -8 terms successfully reproduces JLab data and reveals non-linear QCD dynamics in the small- and low- regime.
This paper utilizes the color dipole picture with a collinear generalized double asymptotic scaling approach to model charm-quark pair production, demonstrating strong agreement with HERA experimental data across a wide kinematic range and confirming the symmetry between saturation and color transparency regions while incorporating threshold mass effects.
This paper investigates the classification and rich spectrum of fully light tetraquark states composed of u, d, and s quarks by analyzing their exotic SU(3) flavor structures within the framework of low-energy Quantum Chromodynamics.
This paper utilizes NuSTAR stray-light X-ray observations to establish the most stringent indirect detection constraints on the lifetimes of various decaying light dark matter candidates, including electrophilic scalars, ALPs, dark photons, and inelastic dark matter, across the keV mass range.
Using neutron interferometry to measure phase shifts in vacuum and low-pressure Argon gas, the study finds no evidence of scalar field couplings and consequently establishes stringent constraints on the symmetron-field model of dark energy.
This paper proposes that introducing an additional scalar field with a matter-like equation of state can dilute gravitino dark matter abundance, thereby resolving the tension between high reheating temperatures needed for thermal leptogenesis and future collider constraints on gluino masses.
This paper systematically analyzes how ultralight dark matter induces distinctive signals in space-based laser interferometers like LISA and Taiji, demonstrating that while laser-frequency variations are suppressed by standard data processing, test-mass oscillations remain detectable and offer significantly improved sensitivity to electron couplings compared to traditional Michelson channels.
This study demonstrates that event-shape engineering in Pb-Pb collisions provides a sharper discrimination between sequential and simultaneous charm hadronization scenarios by revealing a geometry-dependent elliptic-flow splitting () and a species-specific response slope hierarchy that are unique to the sequential model.
This paper analyzes lattice QCD data using unitarized chiral perturbation theory to reveal that the experimental resonance corresponds to a two-pole structure, where a lower pole () behaves like the meson and an upper pole relates to the representation, with their distinct behaviors across chiral trajectories offering new insights into their underlying quark-gluon dynamics.
