Description

Author: Doojin Kim
Abstract: The MiniBooNE low-energy excess remains one of the most prominent anomalies in neutrino experiments, with recent MicroBooNE results reporting a mild excess in the single-photon channel. We propose new scenarios involving light dark matter and/or neutrinos that can simultaneously explain both the MiniBooNE and MicroBooNE excesses. Our framework introduces photons produced via 2-to-3 scattering processes between neutrinos or dark matter and nuclei, mediated by light particles. We identify viable regions in parameter space consistent with current constraints and highlight that these scenarios can be probed by upcoming experimental data.
