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 crossover QCD phase transition in the early Universe led to the formation of stable strangeon nuggets, whose surviving mass density could account for cold dark matter without requiring exotic particles beyond the Standard Model.
This paper investigates the frame dependence of QCD bound states quantized in the temporal gauge under a constant gluon field, deriving their wave functions and demonstrating the Lorentz covariance of electromagnetic form factors for states of any spin.
This paper evaluates the discovery potential of a minimal secluded dark matter model with a kinetically mixed dark photon, demonstrating that while the secluded freeze-out regime is excluded by current constraints, future direct detection and intensity frontier experiments offer complementary sensitivity to the remaining freeze-in and out-of-equilibrium freeze-out parameter spaces.
This paper resolves the ambiguity in mixing between nonlocal gluon and quark bilinear operators by demonstrating that dimensional regularization provides a consistent prescription for handling singularities at zero separation, ensuring agreement between coordinate and momentum space results and compatibility with lattice QCD extractions.
The paper proposes MORRIS, a novel tabletop experiment using a magnetically levitated sub-millimeter particle in a superconducting trap to search for non-Newtonian gravity via a Yukawa-like fifth force, with projected sensitivities that surpass existing bounds for screening lengths around 1 mm.
This paper proposes installing a compact plastic target before the spectrometers of high-energy neutrino experiments like FASER, SHiP, or the Forward Physics Facility to enable the first separate measurement of electron and positron neutrino cross sections, thereby facilitating the study of forward particle production and improving constraints on non-standard neutrino interactions.
This paper analyzes a generalized non-linear electrodynamics model with a photon-background split, demonstrating that a reformulated action generates an effective mass and an additional propagating degree of freedom via a shift from first- to second-class constraints, while ensuring Hamiltonian stability and deriving the corresponding propagator.
This paper pays tribute to the late Toshimitsu Yamazaki by highlighting his pioneering work on deeply bound pionic states and kaonic nuclei, while also presenting recent findings that confirm a deeply bound dibaryon is not excluded by hypernuclei observations but remains too short-lived to be a dark matter candidate.
This paper investigates the Dirac limit of QCD in the large limit, demonstrating that the light quark wave function remains frame-independent and that the discrete bound state spectrum of the theory corresponds to the discrete energies of a Dirac equation with a linear potential.
This paper proposes a supersymmetry model with R-parity violation to explain two rare 8 TeV four-jet events observed by the CMS Collaboration as a heavy down-squark decaying into two lighter first-generation right-handed squarks, while outlining the constraints and predictions for future LHC verification.
