Abstract Details

2019, PhD, University of Cincinnati, Arts and Sciences: Physics.
Most appearance and disappearance neutrino oscillation experiments have observed evidence for neutrino oscillations that agree with the three-flavor neutrino paradigm. Explaining unexpected signal from short-baseline appearance experiments, such as LSND and MiniBooNE, in terms of neutrino oscillations requires the existence of light sterile neutrino(s). The study of light sterile neutrino induced flavor mixing in NOvA uses a long-baseline of 810 km between the Near Detector (ND) at Fermilab and the Far Detector (FD) in Minnesota. The signal for light sterile neutrino-driven oscillations is a deficit of Neutral-Current (NC) neutrino interactions at the FD concerning the ND prediction. In our analysis, we are employing current innovations in machine learning technologies for NC sterile neutrino searches with NOvA. I will detail the state-of-art algorithm which we employed and the improved results obtained in the NOvA NC Disappearance analysis.
