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 explores a classically conformal gauge theory with a triplet dark scalar, identifying three distinct dark matter scenarios—WIMP, supercooled DM, and monopole—that arise from the model's unique first-order phase transition history and analyzing their viability against current constraints and future experimental sensitivities.
This paper investigates potential new physics effects in the semileptonic decays by calculating hadronic form factors within a covariant quark model, constraining Wilson coefficients of four-fermion operators using recent experimental data, and providing theoretical predictions for observables to guide future tests.
This paper evaluates the robustness of collider constraints on the type-II seesaw mechanism by analyzing how motivated extensions of the model alter the production and decay phenomenology of exotic Higgs bosons, thereby potentially modifying standard sensitivity expectations.
This paper presents a theoretical framework and experimental feasibility study demonstrating that muonic kaon atoms can be produced via decays and quark-gluon plasma coalescence at high-energy colliders, offering a novel probe for low-momentum primordial muons and early-time electromagnetic radiation with projected yields sufficient for their first observation.
Using a unified chiral effective field theory framework calibrated with lattice QCD data, this study predicts repulsive interactions for the system while identifying strong attractive forces in the system that support bound states, with significant mass splitting between channels driven by two-pion exchange spin-spin terms.
This paper presents an overview of the McMule Monte Carlo framework and its recent extensions to include low-energy electroweak effects and non-perturbative hadronic contributions via disperon QED, highlighting their applications to precision experiments like MOLLER and the technical challenges of consistent effective field theory matching.
This paper proposes a viable TeV-scale vector-like dark matter candidate within an extended left-right symmetric model featuring an additional $SU(2)$ gauge symmetry, demonstrating its consistency with relic abundance, collider limits, and current direct and indirect detection constraints while highlighting the complementary roles of future multi-ton detectors and the CTA telescope in probing the model's parameter space.
This paper investigates the substructure of quark and gluon jets in photoproduction events at the proposed Electron-Ion Collider using PYTHIA simulations and jet-shape variables, demonstrating the feasibility of distinguishing between these jet types to establish a baseline for future QCD studies.
This paper proposes a novel method to constrain feebly-interacting particles by analyzing the heating and ionization of circumstellar medium around core-collapse supernovae, using non-detections of precursor emission from SN 2023ixf to establish stringent new limits on MeV-scale dark photons.
This paper synthesizes new threshold measurements of production from JLab experiments (007 and CLAS12) with previous GlueX data to confirm a consistent phenomenological determination of the -proton scattering length, while highlighting how upcoming J-PARC measurements will further clarify the systematic trend of vector meson-nucleon interactions predicted by the "young vector meson" hypothesis.
