Systematic Uncertainties in the NOvA Neutrino Oscillation Analysis

Description

NOvA is a long-baseline neutrino oscillation experiment using Fermilab’s 700 kW NuMI muon neutrino beam. It is composed of two detectors which are placed 809km apart and are functionally identical. NOvA studies muon (anti)neutrino disappearance and electron (anti)neutrino appearance and uses these observations to help resolve the mass hierarchy problem and constrain several neutrino oscillation parameters in the standard 3 active neutrinos paradigm: $\theta_{23}$, $\Delta m_{32}^2$, and the CP violating phase $\delta$. While statistical uncertainties currently dominate in these measurements, it is crucial to understand the key sources of systematic uncertainties and their correlations for both the interpretation and precision of the results and for further improvements of the analysis. This poster presents details on how we produce systematically shifted predictions and use them to evaluate the systematic uncertainties affecting NOvA's neutrino oscillation analysis results.
