Abstract

We report results from the first search for nu(mu) -> nu(e) transitions by the NOvA experiment. In an exposure equivalent to 2.74 x 10(20) protons on target in the upgraded NuMI beam at Fermilab, we observe 6 events in the Far Detector, compared to a background expectation of 0.99 +/- 0.11 (syst) events based on the Near Detector measurement. A secondary analysis observes 11 events with a background of 1.07 +/- 0.14 (syst). The 3.3 sigma excess of events observed in the primary analysis disfavors 0.1 pi < delta(CP) < 0.5 pi in the inverted mass hierarchy at the 90% C.L.
