Description
An overview of the recent results from the NOvA muon neutrino disappearance analysis is presented. NOvA is an accelerator based neutrino experiment designed to study the electron neutrino appearance in the muon neutrino beam as it travels from the Near Detector facility at Fermilab to the Far Detector in the Northern Minnesota. The NOvA muon neutrino disappearance group has recently introduced new analysis techniques which greatly improved the experiment's sensitivity. And now for the first time we have data from the beam operating in the antineutrino mode. This, together with an updated detector simulation and new neutrino selection algorithms, allowed NOvA to achieve jointly the world leading estimation of the neutrino oscillation parameter $\Delta m_{23}^2$.
