Results and Prospects from NOvA

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.
