Neutrino Physics at The Short Baseline Near Detector at Fermilab

Iker L. de Icaza, University of Sussex, UK

The Short-Baseline Near Detector (SBND) will be a 112 ton liquid argon time projection chamber (LArTPC) devoted to researching neutrino oscillations. Located 110 m downstream of the Booster Neutrino Beam (BNB) target, SBND is the near detector of the three-detector Short Baseline Neutrino (SBN) program at Fermilab. The SBN program will probe neutrino oscillations at the ~1 eV2 scale. SBND will have a rich cross-section measurement program and is also a testbed for R&D of new technology. Additionally, the detector's fine spatial resolution and relative high rate of interactions, make it a prime candidate to look for BSM physics. In this talk, I'll give an overview of the LSND and MiniBooNE anomalies, the current landscape of oscillations at this scale, and briefly discuss the shrinking potential for light sterile neutrinos to explain observations. I'll present a novel dark sector model that tackles MiniBooNE's low energy excess, and simulations of this exotic interaction in SBND. I'll conclude with an overview of the future of LArTPC neutrino experiments and DUNE.
