The Tokai-to-Kamioka (T2K) experiment is a long-baseline neutrino-oscillation experiment that searches for neutrino oscillations with measurements of an off-axis, high purity, muon neutrino beam. The neutrinos are detected 295 km from production by the Super Kamiokande detector. A near detector 280 m from the production target measures the unoscillated beam. This thesis outlines an analysis using samples in the near detector and Super Kamiokande to measure the disappearance of muon neutrinos. To manage the complexity this analysis, a Markov Chain Monte Carlo framework was used to maximize a likelihood to estimate the oscillation parameters. T2K Run 1+2+3 data (3.010 x10²⁰ POT) is used for the analysis. The estimates for the oscillation parameters are: ( sin² (2θ₂₃ ), Δ m²₃₂ ) = (0.999,2.45 x10ˉ³ [eV²]), and the 90% 1D bayesian credible intervals: 0.9340 < sin² (2θ₂₃ ) < 1.000 2.22 x10ˉ³ < Δm²₃₂ [eV²] < 2.74 x 10ˉ³ / Graduate / 0798

Observed disappearance of reactor antineutrinos in the short baseline in Daya Bay can be explained by the phenomenon of neutrino flavour oscillations. The analysis in standard three- neutrino framework provides the best measurement of mixing angle of θ13 and the value of effective mass squared difference ∆m2 ee with comparable precision with other experiments. The unprecedented precision of Daya Bay motivates us to extend our search beyond standard three-neutrino oscillation scheme. It this thesis, we have explored two scenarios of possible physics Beyond Standard Model (BSM). We have tested the fundamental symmetry of the nature by searching for the Lorentz Invariance violation effect within the framework of the Standard-Model Extension (SME). Such an effect could be observed as a deviation from three- neutrino oscillation prediction in the oscillated antineutrino spectrum. Since we have not observed any significant deviation, we have been able to set the limits on the SME parameters. Some of the limits were measured for the first time while some turned out not to be competitive with the measurement of other experiments. We have also performed search for Non-standard Interactions (NSIs) in the Daya Bay. Being forbidden in the Standard Model, these interactions are predicted by BSM theories for which...
