Signatures for New Physics in Short-Baseline Liquid Argon Neutrino Experiments

PHY Colloquium

Abstract: Searches for New Physics have been the domain of high-energy colliders for decades. Recently, there is a growing interest in exploring similar/complementary opportunities in neutrino experiments. Liquid Argon Time Projection Chamber (LAr TPC) detectors at Short-Baseline are ideal tools to look for new physics in the neutrino sector and beyond.

ArgoNeuT, a small LAr TPC exposed to the Neutrinos at the Main Injector beam at Fermilab, provided leading constraints on New Physics in unexplored parameter space regions. The LAr TPC detectors of the Short-Baseline Neutrino (SBN) program sitting on the Booster Neutrino Beam at Fermilab will perform a world-leading search for eV-scale sterile neutrinos. Beyond the flagship oscillation searches, the SBN program has a broad science goal addressing alternative explanations of short-baseline neutrino anomalies and including other Beyond Standard Model explorations.
