Global status of neutrino oscillation parameters after recent reactor
measurements
   [PDF]

M. Tórtola, J. W. F. Valle, D. Vanegas
Here we update the global fit of neutrino oscillations in Refs. \cite{Schwetz:2011qt,Schwetz:2011zk} including the recent measurements of reactor antineutrino disappearance reported by the Double CHOOZ, Daya Bay and RENO experiments. We find that the preferred global fit value of $\theta_{13}$ is quite large: $\theta_{13} = 0.026 (0.027)$ for normal (inverted) neutrino mass ordering, while $\sin^2\theta_{13} = 0$ is now excluded at 8$\sigma$. The impact of the new $\theta_{13}$ measurements over the other neutrino oscillation parameters is also discussed.
