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.
Using a diffusion Monte Carlo algorithm within a constituent quark model, this study demonstrates that explaining the observed and pentaquarks requires the total wavefunction to be an eigenvector of the SU(3) flavor operator, a condition that yields two mass-compatible structures and predicts additional states below the threshold, whereas imposing only isospin symmetry results in a single structure.
This paper proposes a novel LHC search for GeV-scale particles coupling to light quarks by identifying low-multiplicity jets produced in association with a hard photon, a signature that distinguishes these signals from standard QCD backgrounds and extends the discovery reach into previously inaccessible parameter space.
This paper investigates a dark matter model consisting of millicharged magnetic monopoles from a dark U(1) sector with kinetic mixing to the Standard Model, deriving constraints on its parameters from dark matter self-interactions and the survival of galactic magnetic fields via the Parker effect across three distinct phenomenological scenarios.
This paper demonstrates that accounting for hadrons produced via ion electromagnetic dissociation, which break experimental exclusivity vetos, resolves long-standing tensions between theoretical predictions and LHC measurements for exclusive muon pair and coherent production.
This paper demonstrates that upcoming ultra-high-energy tau neutrino experiments like GRAND and POEMMA will provide significantly more stringent constraints on Lorentz invariance violation than current low-energy probes by analyzing deviations in flavor transition probabilities and event rates across single and multiple LIV operator scenarios.
This paper investigates the sensitivity of neutrino observatories and direct detection experiments to sub-GeV dark matter boosted by cosmic ray bremsstrahlung in the atmosphere, specifically modeling initial state radiation and resonances to extend mass limits and compare the capabilities of LZ, PandaX-4T, Borexino, and Super-K.
Using DESI DR1 data, this study analyzes 23 nearby extreme emission-line galaxies with a multi-element Bayesian chemical-evolution model to reveal that their rapid gas cycling and chemical enrichment are driven by bursty star formation, regulated by outflows, and constrained by inflow metallicity.
This paper introduces a graph-theoretic method that determines the number and localization of massless fermion modes in latticized theory-space models by analyzing the maximum matching and Dulmage-Mendelsohn decomposition of bipartite graphs representing mass terms, providing a parameter-independent tool for systematic model construction.
This paper solves the Dyson-Schwinger equations for the Landau gauge quark-gluon vertex in quenched QCD to demonstrate that while its transverse form factors exhibit weak angular dependence, this does not constitute planar degeneracy, while simultaneously confirming that dynamical chiral symmetry breaking relies on a mutually generated tensor coupling and that the resulting quark propagator is consistent across different Yang-Mills solutions with poles only on the real time-like axis.
This paper introduces a fast and reliable three-flavor neutrino oscillation calculator for constant-density matter that combines analytic perturbative formulas with exact diagonalization to enable rapid, uncertainty-propagated probability calculations for current and future long-baseline experiments.
