Description

The primary goal of the NOvA experiment is to perform sensitive searches for standard three-flavor neutrino oscillations. The experiment is designed to measure electron-neutrino appearance at the Far Detector using the Near Detector to control systematic uncertainties; however, the Near Detector is well suited for searching for possible anomalous short-baseline oscillations. The LSND and MiniBooNE experiments obtained hints of electron-antineutrino appearance, which does not fit the three-flavor neutrino paradigm and can be explained by the addition of a sterile neutrino at a larger mass scale than the existing three-flavor mass states. This talk will present a novel method for selecting tau neutrino interactions at the Near Detector using a convolutional neural network. Based on this method, this talk will present NOvA's sensitivity to anomalous short-baseline tau-neutrino appearance and muon neutrino disappearance due to sterile neutrino oscillations.
