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 proposes a two-loop rainbow neutrino mass model based on a gauged subgroup of a non-invertible symmetry, which simultaneously explains neutrino oscillations, provides a stable vector-like fermion dark matter candidate, and predicts a sum of neutrino masses in the normal hierarchy that exceeds that of the inverted hierarchy.
This paper investigates how decay channels influence near-threshold mass scaling using potential models, demonstrating that the pole of a quasibound state below the threshold is not continuously connected to that of a resonance state above the threshold, while clarifying the correspondence between single-channel complex and coupled-channel real potential approaches.
By combining DESI DR1 full-shape galaxy clustering data with CMB, BAO, and supernova observations, this study achieves percent-level cosmological constraints that significantly tighten limits on the sum of neutrino masses and provide robust evidence for the normal neutrino mass hierarchy, while also revealing a mild preference for dynamical dark energy.
This study employs a transport approach to demonstrate that photon-tagged jets effectively mitigate selection bias, thereby revealing medium-induced angular broadening in PbPb collisions that contrasts with the narrowing observed in inclusive jets.
This paper employs a bottom-up approach to analyze one and two texture zeros in the neutrino mass matrix using current oscillation data, identifying specific allowed vanishing elements for normal and inverted mass orderings while establishing correlations between the lowest neutrino mass and CP-violating phases.
This paper investigates a second-order extension of perfect spin hydrodynamics in a boost-invariant expansion, finding that while spin dynamics feedback constrains polarization configurations, the resulting behavior remains nearly identical to the non-feedback case as long as the spin polarization magnitude stays below unity.
This study utilizes QCD light-cone sum rules to calculate the magnetic moments of tetraquark states, demonstrating that these electromagnetic properties can effectively distinguish between different internal structures and spin-parity configurations despite similar masses.
This paper presents a sensitivity study demonstrating that the CEPC operating at a center-of-mass energy of 360 GeV, with an integrated luminosity of 1.0 ab, has the potential to discover direct stau pair production up to masses of approximately 170 GeV and smuon pair production up to 178 GeV.
This paper presents a combined thermal and coalescence model for heavy-ion collisions in the few-GeV regime that successfully reproduces proton, pion, and deuteron yields but underpredicts the production of H and He nuclei by a factor of two compared to experimental data.
This paper investigates the application range of perfect spin hydrodynamics in both classical and quantum frameworks by analyzing the relationships between spin polarization, particle mass, temperature, and hydrodynamic flow, providing insights crucial for modeling heavy-ion collisions.
