Recent results from NOvA

Abstract

We present the most recent 3-flavor neutrino oscillation results from the NOvA long-baseline experiment, using a joint fit of ${\nu }_{\mu }\to {\nu }_{\mu }$, ${\bar{\nu }}_{\mu }\to {\bar{\nu }}_{\mu }$, ${\nu }_{\mu }\to {\nu }_e$, and ${\bar{\nu }}_{\mu }\to {\bar{\nu }}_e$ channels, and an accumulated exposure of $13.6\times 10^{20}$ protons-on-target of neutrino beam and $12.5\times 10^{20}$ protons-on-target of antineutrino beam. The best-fit values for the atmospheric parameters are $\Delta m_{32}^2=(2.41\pm 0.07)\times 10^{-3}$ eV${}^2$, ${\sin }^2{\theta }_{23}=0.57_{-0.04}^{+0.03}$ and ${\delta }_{CP}=(0.82_{-0.87}^{+0.27})\pi$. The data disfavor combinations of oscillation parameters that lead to large asymmetries between the rates of ${\nu }_e$ vs ${\bar{\nu }}_e$ appearance.
