Abstract
Using a beam made (mainly) by muon neutrinos traveling through the earth, the NOvA Experiment looks for the appearance of electron neutrinos, a transformation explained by the quantum-mechanical phenomenon known as neutrino oscillation. NOvA uses two neutrino detectors located 14.6 mrad off-axis from the main beam direction. The first (Near) detector stands at a distance of 1 km from the neutrino source, while the second (Far) one is at 810 km. Traveling from the Near Detector to the Far Detector, muon neutrinos can morph into electron neutrinos with a probability depending upon the parameters and sin2 θ23, among others. By comparing the observed number of νµ and νe events at the Far Detector with the expected number of events predicted by a 3-neutrino oscillation model, NOvA is able to measure these parameters and help to improve our understanding about neutrinos. After a brief introduction to the physics of neutrinos and a presentation of the experiment, in this talk the most recent results obtained by NOvA through the study of muon neutrino oscillations νµ → νµ and νµ → νe, are shown. The oscillation parameters are found to be and sin2 θ23 = 0.56.
