NOvA is an experiment devoted to studying neutrino oscillations in the NuMI neutrino beam from FNAL (USA). It is a long-baseline experiment consisting of two functionally identical, finely granulated detectors which are separated by 810 km of Earth crust and sited at 14 mrad off the beam axis. By measuring the transition probabilities P(νμ→νe \nu_\mu \rightarrow \nu_e ) and P(νμ→νμ \nu_\mu \rightarrow \nu_\mu ) NOvA is able to extract oscillation parameters: Δm232 \Delta m^2_{32} , mixing angle θ23 \theta_{23} , CP violating phase δCP \delta_{CP} and neutrino mass hierarchy. This analysis will be the first to include both neutrino (9⋅1020 9 \cdot 10^{20} POT) and antineutrino (7⋅1020 7 \cdot 10^{20} POT) data, which helps to resolve degeneracies in the oscillation probability. In this poster, the lastest NOvA oscillation results will be discussed, as well as important intermediate steps in νe \nu_e analysis like signal and background predictions, projected sensitivities in upcoming analyses will be presented.
