The Standard Model of particle physics (SM) is the most well tested model in existence. The only departure from its original formulation to date is the observation of neutrino oscillations, implying finite neutrino masses. The mixing of neutrino flavour and mass states, analogous to that of the quarks, provides an additional CP-violating phase (delta-CP) to the SM which is accessible through long baseline neutrino oscillations. The Tokai-to-Kamioka (T2K) experiment, located in Japan, samples a neutrino beam generated at the J-PARC proton accelerator close to the production point with a complex of near detectors and far away from it with the Super-Kamiokande detector. The observation of electron neutrino appearance in a muon neutrino beam by T2K has paved the way to CP violation studies in long baseline experiments. The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino experiment located in the US that uses novel liquid argon time projection chamber technology and has as one of its primary goals the determination of delta-CP using an intense neutrino beam produced at Fermilab. In this seminar I will report the latest neutrino oscillation results from T2K and discuss the prospects for the precise measurement of neutrino mixing parameters with DUNE.
