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 study utilizes the UrQMD transport model to analyze baryon stopping in low-energy Au+Au collisions, revealing that a significant fraction of mid-rapidity protons originate from initial neutrons via isospin conversion, a process that deviates from chemical equilibrium assumptions below 10 GeV and is coupled with the onset of nuclear transparency.
This paper proposes that a recent LUX-ZEPLIN event can be explained by GUT-induced pseudo-Dirac dark matter, which predicts a boson with a mass in the tens of TeV range that is within the discovery reach of the Future Circular Collider (FCC-$hh$).
This paper proposes that boosted light magnetic dipole-dipole dark matter, produced via the annihilation of heavier halo dark matter, offers a viable explanation for the LZ collaboration's reported nuclear-recoil excess by resolving the tension between TeV-scale fits and the lack of low-energy events while also allowing for GeV-scale dark matter candidates.
This paper demonstrates that while Solar capture constraints definitively exclude the thermal Higgsino interpretation of the recent LZ high-recoil event, they do not generically rule out other endothermic dark matter models, such as thermal pseudo-Dirac fermions or neutron-philic spin-dependent scattering, which remain viable despite being significantly below current IceCube limits.
This paper proposes a novel modular symmetry framework that unifies Dirac neutrino mass generation with inelastic self-interacting dark matter, successfully explaining the LUX-ZEPLIN 248 keV event while predicting a stochastic gravitational wave background from the annihilation of cosmological domain walls.
This paper proposes that the 248-keV nuclear recoil event observed by the LUX-ZEPLIN experiment could be explained by light boosted dark matter scattering off xenon nuclei, offering a model-independent alternative to heavy halo dark matter interpretations that rely on uncertain high-velocity tails of the Galactic velocity distribution.
This paper demonstrates that a previously proposed inelastic scalar dark matter model within a gauged framework naturally explains the recent high-energy recoil event observed by the LUX-ZEPLIN collaboration while satisfying thermal relic constraints, offering a testable scenario for future boson searches.
Using the Schwinger proper-time Nambu-Jona-Lasinio model, this study investigates the electromagnetic structure of the meson in symmetric nuclear matter, revealing that its charge, magnetic, and quadrupole form factors are suppressed with increasing density and that its in-medium charge radius is approximately 0.74 fm.
This paper proposes a minimal realization of spontaneous leptogenesis within the type-II seesaw model, demonstrating that a rotating Majoron background can generate lepton and Higgs asymmetries through decay and inverse-decay processes without requiring additional scalar triplets or explicit CP-violating interactions.
This paper investigates the sensitivity of Future Circular Collider-hadron electron (FCC-he) collisions to neutral Triple Gauge Couplings within the Standard Model Effective Field Theory framework, demonstrating that the resulting constraints on dimension-8 operators are comparable to current LHC limits and superior to those expected from CEPC experiments.
