Abstract

The Tokai-to-Kamioka (T2K) experiment is a second generation longbaseline neutrino experiment and the �rst to use an o�-axis neutrino beam to produce narrow neutrino energy spectrum. T2K was designed to measure with precision the atmospheric mixing parameters, and also look for evidence of non-zero �13. T2K's near detector (ND280) provides constraints on the beam ux and neutrino cross-section uncertainties, as well as making valuable cross-section measurements. This thesis describes an oscillation analysis that uses samples from both near and far detectors. Importantly, �� and �e samples at the far detector are combined to produce a joint oscillation analysis. A Markov chain Monte Carlo is used to construct the Bayesian posterior distribution by sampling a likelihood function. From the Bayesian posterior distribution, the oscillation parameters of interest and their errors are estimated. When analysing with only T2K run 1-4 data, the best �t point for the oscillation parameters is �m2 32 = (
