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 that a heavy higgsino dark matter candidate with a mass of approximately 0.1 PeV can explain the universe's dark matter abundance and the recent LUX-ZEPLIN high-recoil event without violating detection constraints, provided the reheating temperature is suppressed below 595 GeV through the non-thermal production of higgsinos from the decay of a heavy modulus field.
This paper constrains an ultra-light vector boson from the gauged model using solar neutrino oscillation data, finding a potential best-fit scenario that slightly improves upon the standard three-flavour model while projecting significant future refinements from JUNO and XLZD experiments.
This paper proposes that if the recent high-energy nuclear-recoil candidate observed by LUX-ZEPLIN (LZ) is caused by endothermic dark matter upscattering, the same mass splitting would produce a sub-MeV gamma-ray line detectable by the upcoming COSI mission, thereby offering a critical test for this dark matter interpretation.
This paper investigates the spectral stability of quasinormal modes in nonconformal holographic QCD models using pseudospectral analysis, revealing that increasing temperature drives a progressive loss of coherence in hadronic excitations and that pseudospectral instability serves as a complementary diagnostic for hadronic dissociation and melting.
This paper argues that Muru et al.'s conclusion regarding the indistinguishability of dark matter and stellar population morphologies for the Galactic Center Excess is invalid because they incorrectly used the square of the projected mass density instead of the proper annihilation integral, and a corrected calculation on the same simulations refutes their claim.
This paper demonstrates that relic neutrinos preserve a record of post-decoupling electromagnetic entropy production, enabling the derivation of a specific response kernel that links small-scale primordial non-Gaussianity to observable relic neutrino capture rates through the filtering of excited initial states.
This paper improves the accuracy of Light-Front Holographic QCD in predicting the radial excitation spectra of light pseudoscalar and vector mesons by extending the standard soft-wall transverse potential with Coulombic and logarithmic terms, thereby reducing the average deviation from experimental data by approximately 32%.
This paper develops a new effective hadronic theory called Soft-Collinear Chiral Perturbation Theory to systematically describe form factors at large recoil by exploiting a duplicated chiral symmetry, ultimately revealing that its predicted chiral-logarithmic corrections differ from those of existing Hard-Pion Chiral Perturbation Theory.
This paper challenges the long-held belief that newborn quark stars are inefficient emitters by demonstrating that their electrospheres can produce significant electromagnetic radiation, leading to a two-stage cooling process characterized by an initial days-long phase of MeV-to-keV blackbody emission followed by a fading 40 keV spectral feature.
This paper summarizes recent progress on four-loop QCD splitting functions, highlighting that while the three non-singlet cases are now fully determined with some unexpected small- double logarithms, the flavour-singlet sector reveals novel analytical structures, with overall numerical effects remaining below 1% for most parton distributions down to .
