Description
NOvA is long-baseline neutrino oscillation experiment with functionally identical liquid scintillator detectors separated by a long-baseline, in the NuMI neutrino beam at Fermilab. NOvA probes not only the standard three flavor scenario, but also exotic oscillations scenarios including sterile neutrinos and non-standard interactions. The 3+1 sterile oscillation model is an extension of the standard three flavor oscillation paradigm which includes an extra neutrino mass and flavor eigenstate, where the new flavor state does not interact with the weak force. NSI are an extension of the neutrino matter effect, including off-diagonal terms, which augment the phenomenology of the three flavor oscillation paradigm. This talk summarizes recent beyond-the-Standard-Model neutrino oscillation results from NOvA, including a search 3+1 sterile oscillations that utilizes charged current muon neutrino and neutral current selections in a two-detector fit procedure to place robust limits on multiple sterile mixing parameters, and a search for NSI utilizing charged current muon and electron neutrino samples in both neutrino and antineutrino beam modes.
