Abstract
NOvA is a long-baseline experiment studying primarily neutrino oscillations in the NuMI beam from Fermi National Laboratory (FNAL), USA. It consists of two functionally identical, finely granulated detectors which are separated by 810 km and situated 14.6 mrad off the NuMI beam axis from FNAL. By measuring the transition probabilities P(vμ → ve ) and P(vμ → vμ ), NOvA is able to probe the following parameters: , the mixing angle θ 23, the CP violating phase δCP and the neutrino mass hierarchy. This document is devoted to the latest NOvA measurements of the neutrino oscillation parameters using neutrino and antineutrino disappearance and appearance obtained in 2020.

Summary
NOvA [1] is a long-baseline experiment devoted to studying neutrino oscillations in the muon (anti-)neutrino beam. The Near Detector (ND) has dimension 4.2 m × 4.2 m × 16 m and 300 t mass It is placed about 1 km after the target and used for measuring unoscillated neutrino beam composition.
