NOvA is a long baseline neutrino oscillation experiment using two functionally equivalent detectors to make precision neutrino oscillation measurements utilizing the NuMI beam at Fermilab. The two detectors are situated 14 mrad off the beam axis, one located at Fermilab and the second located 810 km away in Minnesota. NOvA observes the oscillation of neutrinos and anti-neutrinos over this 810 km baseline and measures the parameters associated with oscillations such as the neutrino mass hierarchy and the neutrino mass splitting and mixing in the 2-3 sector. Key to these measurements are an understanding and rigorous treatment of the systematic uncertainties from many sources: neutrino interaction modeling, detector calibration and response, flux uncertainty, and others. I will present details of the systematic uncertainties affecting NOvA and how these uncertainties are evaluated for NOvA’s latest joint electron and muon (anti)neutrino oscillation results.
