T2K and T2K+SK results

Type: conference-paper
Abstract: Tokai-to-Kamioka (T2K) is a long-baseline neutrino oscillation experiment which utilizes a neutrino beam produced at the Japan Particle Accelerator Research Center. The composition and energy of the oscillated neutrino spectrum are measured using the Super-Kamiokande (SK) water Cherenkov detector located 295km downstream. Significant updates have been made to previous oscillation analyses, resulting in charge-parity (CP) violation being excluded at 90% confidence level. In addition, a T2K+SK joint analysis of beam and atmospheric neutrinos has been performed which strengthens the exclusion of CP-violation to 1.9π. The Bayes factor for normal hierarchy preference, as calculated by the joint analysis, is found to be π΅(ππ»/πΌπ») = 8.98.
