Introduction -- Overview of the T2K experiment -- The Fine-Grained Detector -- Pion Interaction measurement at TRIUMF M11 Beamline -- Extraction of Pion Absorption and Charge Exchange Cross Section -- Improvement of pion interaction model -- Monte Carlo Simulation for the Oscillation Analysis -- Near Detector Measurement -- Far Detector Measurement -- Oscillation Analysis and Results -- Conclusion.

<p>In this thesis the author contributes to the analysis of neutrino beam data collected between 2010 and 2013 to identify νμ→νe events at the Super-Kamiokande detector. In particular, the author improves the pion–nucleus interaction uncertainty, which is one of the dominant systematic error sources in T2K neutrino oscillation measurement. In the thesis, the measurement of νμ→νe oscillation in the T2K (Tokai to Kamioka) experiment is presented and a new constraint on δCP is obtained. This measurement and the analysis establish, at greater than 5σ significance, the observation of νμ→νe oscillation for the first time in the world. Combining the T2K νμ→νe oscillation measurement with the latest findings on oscillation parameters including the world average value of θ13 from reactor experiments, the constraint on the value of δCP at the 90% confidence level is obtained. This constraint on δCP is an important step towards the discovery of CP violation in the lepton sector.</p>.
