Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19
We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

indico search will be reestablished in the next version upgrade of the software: https://getindico.io/roadmap/

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.
