A non zero, surprisingly large value of the third mixing angle θ13 has been measured in reactor neutrino experiments. Currently the most precise measurement of sin2 2θ13 has been performed by the Daya Bay experiment sin22θ13=0.089± 0.010(\rm stat.)±0.005(\rm syst.) (7.7 σ significance of sin22θ13 > 0),the RENO experiment has measured the value sin2 2θ13 = 0.113 ± 0.013(\rm stat.) ± 0.019(\rm syst.) (4.9 σ significance) and the Double Chooz experiment sin2 2θ13 = 0.109 ± 0.030(\rm stat.) ± 0.025(\rm syst.) (2.9 σ significance). These results are extremely important for future searches of violation of combined CP parity in lepton sector of the Standard model.
