Abstract

The NOvA experiment is a two-detector long-baseline neutrino experiment for addressing the main open questions in neutrino oscillation physics through precision measurements of neutrino and antineutrino oscillations. It uses the NuMI beam from FNAL and a finely segmented 14-kton far detector at Ash River, Minnesota. The "fully active" detector design provides outstanding event identification capacity, which allows precision measurement of oscillation parameters in both appearance and disappearance of neutrinos and anti-neutrinos. In particular constraints will be obtained on theta_13, theta_23, |Delta M^2_atm|, neutrino mass ordering and the CP-violation phase. I will report on results from the first phase using 8 percent of the nominal exposure.
