Writing in Physical Review Letters, the T2K collaboration reports the strongest evidence to date for the appearance of electron neutrinos from a pure muon neutrino beam. Their measurement allows them to determine a fundamental parameter of the standard model of particle physics, calledZz.
θ13, which can in turn be used to make an early estimate of CPviolation in neutrinos. Although this estimate has a large uncertainty, it will serve as a guide to future, more definitive neutrino experiments that are directly sensitive to CPviolation.

Electron Neutrino Appearence In Muon Neutrino Beam
Another and clearer detection of the appearance of electron neutrino from muon neutrino beam due to flavor mixing. This one is from the T2K collaboration. The link give you access to the actual paper in PRL.
