Abstract

We present the most recent 3-flavor neutrino oscillation results from the NOvA long-baseline experiment, using a joint fit of νμνμ\nu_\mu \to \nu_\mu, νˉμνˉμ\bar{\nu}_{\mu} \to \bar{\nu}_{\mu}, νμνe\nu_\mu \to \nu_{e}, and νˉμνˉe\bar{\nu}_{\mu}\to \bar{\nu}_{e} channels, and an accumulated exposure of 13.6×102013.6 \times 10^{20} protons-on-target of neutrino beam and 12.5×102012.5 \times 10^{20} protons-on-target of antineutrino beam. The best-fit values for the atmospheric parameters are Δm322=(2.41±0.07)×103\Delta m^2_{32} = (2.41\pm0.07)\times 10^{-3} eV2^2, sin2θ23=0.570.04+0.03\sin^2\theta_{23} = 0.57^{+0.03}_{-0.04} and δCP=(0.820.87+0.27)π\delta_{CP} = (0.82^{+0.27}_{-0.87}) \pi. The data disfavor combinations of oscillation parameters that lead to large asymmetries between the rates of νe\nu_{e} vs νˉe\bar{\nu}_{e} appearance.
