# Observation of _ _e Oscillation in the T2K Experiment

##### Beskrivning:

In this thesis theauthor contributes to the analysis of neutrino beam data collected between 2010and 2013 to identify e events at the Super-Kamiokande detector. In particular,the author improves the pion-nucleus interaction uncertainty, which is one ofthe dominant systematic error sources in T2K neutrino oscillation measurement.In the thesis, the measurement of e oscillation in the T2K (Tokai toKamioka) experiment is presented and a new constraint on CP is obtained. Thismeasurement and the analysis establish, at greater than 5 significance, theobservation of e oscillation for the first time in the world. Combiningthe T2K e oscillation measurement with the latest findings on oscillationparameters including the world average value of 13 from reactor experiments,the constraint on the value of CP at the 90% confidence level is obtained.This constraint on CP is an important step towards the discovery of CPviolation in the lepton sector.
