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.
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.
This paper investigates how axion condensates within neutron stars, modeled using the BSk26 equation of state, alter the stars' equilibrium structure and radial oscillation spectrum by introducing a distinct family of highly damped axion modes and axion-induced damping effects that could potentially enable neutron star seismology to probe axion properties.
This paper proposes a novel neural network-based method for estimating fake lepton backgrounds in high-energy physics by performing density ratio estimation in a high-dimensional feature space, which offers a more precise, flexible, and continuous alternative to traditional binned histogram techniques while reducing binning artifacts and improving extrapolation.
This paper presents a slim, quantized, and parameter-reduced version of the L-GATr jet tagger that achieves an order-of-magnitude reduction in energy cost with only a moderate performance decrease, paving the way for efficient trigger-level jet tagging at the LHC.
This study utilizes the Hadron Resonance Gas model in Partial Chemical Equilibrium to analyze Au+Au collisions at RHIC energies, revealing that baryon annihilation ceases between chemical and kinetic freeze-out and demonstrating that inelastic hadronic interactions significantly shape the final hadron composition.
