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 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 paper demonstrates that event-shape engineering in Pb-Pb collisions provides a sharper discrimination between sequential and simultaneous charm hadronization scenarios by revealing that the - elliptic-flow splitting exhibits a distinct, species-dependent response to initial geometry () in the sequential model, which is absent in the conventional baseline.
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.
This paper investigates the space-like Sachs electric and magnetic form factors of baryons in asymmetric nuclear matter at finite temperature using a vector meson dominance model coupled with QCD sum rules and a chiral SU(3) quark mean field framework, while also calculating in-medium charge radii and comparing the results with existing phenomenological models, lattice simulations, and experimental data.
This paper demonstrates that higher-dimensional marginal operators significantly weaken cosmological phase transitions and introduce substantial uncertainties in gravitational-wave predictions, potentially causing the high-temperature expansion to break down for transitions strong enough to be detected by LISA.
This paper tests the star-disk collision model for quasiperiodic eruptions using shock-cooling emission constraints on stellar radius and temperature, finding that the simplest version of the model fails to simultaneously explain the observed peak luminosities, durations, and radiation temperatures for most sources in the sample.
This paper establishes a first-principles framework based on non-local Kadanoff-Baym equations that unifies macroscopic fluid dynamics and microscopic particle interactions to systematically determine bubble wall velocity, revealing a linear friction force from scattering that prevents runaway bubbles in the ballistic regime.
