A non zero, surprisingly large value of the third mixing angle $\theta_{13}$has been measured in reactor neutrino experiments. Currently the most precisemeasurement of $\sin^2 2\theta_{13}$ has been performed by the Daya Bayexperiment $\sin^22\theta_{13}=0.089\pm 0.010({\rm stat.})\pm0.005({\rmsyst.})$ (7.7 $\sigma$ significance of $\sin^22\theta_{13} > 0$),the RENOexperiment has measured the value $\sin^2 2\theta_{13} = 0.113 \pm 0.013(\rmstat.) \pm 0.019(\rm syst.)$ (4.9 $\sigma$ significance) and the Double Choozexperiment $\sin^2 2\theta_{13} = 0.109 \pm 0.030(\rm stat.) \pm 0.025(\rmsyst.)$ (2.9 $\sigma$ significance). These results are extremely important forfuture searches of violation of combined CP parity in lepton sector of theStandard model.
