Title: Electron neutrino appearance in the NOvA experiment

Abstract

NOvA is an off-axis, two-detector experiment studying neutrino oscillations with the ν(µ) beam from Fermilab. This paper describes the ν e appearance analysis, including data-driven constraints from Near Detector measurements. The data set corresponds to an exposure equivalent to 6.05 × 10 20 protons-on-target in the Far Detector. Here, we observed 33 ν e candidates with a predicted background of 8.2 ± 0.8 (syst.), for a significance of appearance higher than 8σ. Preliminary results for the allowed values of δ CP and θ 23 in both hierarchies are presented.
