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 a high-quality axion model where the axion arises as a pseudo-Nambu-Goldstone boson of baryon number symmetry in a composite sector (such as SQCD with ), naturally suppressing dangerous symmetry-breaking operators due to the high dimension of the baryon operator while generating the required coupling to gluons through flavor symmetry anomalies.
This paper proposes a radiative lepton mass model based on a non-invertible gauging of a fusion rule, where charged-lepton masses arise from dynamical symmetry breaking while neutrino masses are generated without breaking the rule, leading to testable predictions for lepton flavor violations, anomalous magnetic moments, electric dipole moments, and neutrinoless double beta decay that align with experimental data.
This paper proposes that dark matter is not a new particle but an emergent, dynamical state arising from the interaction between a three-form gauge field and the cosmic fluid, offering a unified framework for the dark sector that suggests conventional dark matter searches may be futile.
The paper introduces HadroTOPS, a flexible Monte Carlo event generator designed to simulate hadronic two-photon fusion events in electron-positron collisions with exact leading-order QED coupling and customizable phase space decays, specifically supporting partial wave analyses for various final states relevant to collaborations like BESIII.
This paper proposes that General Relativity can be modeled as a degenerate Otto cycle in emergent gravity, where introducing work-producing legs generates controlled Lorentz and energy-momentum violations that drive late-time cosmological acceleration.
This paper proposes that slow first-order phase transitions involving the collision of only two vacuum bubbles generate a unique signature of linearly polarized gravitational waves, which could be detected by future interferometers like LISA and the Einstein Telescope to probe the early universe.
This review argues that despite potential flaws in the assumption of near-simultaneous neutrino emission from SN 1987A, the data may still yield specific values for the three neutrino masses that exceed current cosmological and experimental upper limits, as originally suggested by Ramanath Cowsik.
This paper investigates the sensitivity of LHC displaced vertex searches to electroweak pair-produced heavy neutral leptons within a supersymmetric higgsino decay framework, deriving constraints from ATLAS Run 2 data and projecting discovery potential for the HL-LHC while assessing the generalizability of these results to broader models.
This paper proposes a solution to the long-standing gallium anomaly by revising the theoretical calculation of the neutrino capture cross-section on Ga, demonstrating that moving beyond standard leptonic wave function factorization and incorporating constrained Gamow-Teller transition densities can resolve the observed deficit without invoking new physics.
This paper proposes a data-driven calibration strategy using B solar neutrinos and muon-decay-at-rest neutrinos as standard candles to constrain the poorly known electron neutrino-argon cross section, thereby significantly reducing model-dependent biases in extracting Galactic supernova spectral properties at the DUNE experiment.
