Abstract

The T2K collaboration has combined the νμ\nu_{\mu} disappearance and νe\nu_e appearance data in a three-flavor neutrino oscillation analysis. A Markov chain Monte Carlo results in estimates of the oscillation parameters and 1D 68% Bayesian credible intervals at δCP=0\delta_{CP} = 0 as follows: sin2θ23=0.5200.050+0.045\sin^{2}\theta_{23} = 0.520^{+0.045}_{-0.050}, sin2θ13=0.04540.014+0.011\sin^{2}\theta_{13} = 0.0454^{+ 0.011}_{-0.014} and Δm322=2.57±0.11|\Delta m^{2}_{32}| = 2.57\pm0.11, with the point of highest posterior probability in the inverted hierarchy. Recent measurements of θ13\theta_{13} from reactor neutrino experiments are combined with the T2K data resulting in the following estimates: sin2θ23=0.5280.038+0.055\sin^{2}\theta_{23} = 0.528^{+0.055}_{-0.038}, sin2θ13=0.0250±0.0026\sin^{2}\theta_{13} = 0.0250 \pm 0.0026 and Δm322=2.51±0.11|\Delta m^{2}_{32}| = 2.51\pm0.11, with the point of highest posterior probability in the normal hierarchy. Furthermore, the data exclude values of δCP\delta_{CP} between 0.14π\pi-0.87π\pi with 90% probability.
