Abstract
NOvA is a long-baseline neutrino experiment that uses an upgraded NuMI neutrino source at Fermilab and a 14-kton detector at Ash River, Minnesota. The detector has a highly active,
finely segmented design that offers superb event identification capability. This talk presents the latest $\nu_\mu$ ($\bar{\nu}_\mu$) disappearance and $\nu_e$ ($\bar{\nu}_e$) appearance combined results using the first NOvA anti-neutrino beam data. In the far detector, 18 $\bar{\nu}_e$ candidate events are observed, with a significance of $\bar{\nu}_e$ appearance more than 4 $\sigma$. The NOvA results favor a normal neutrino mass hierarchy.
