The T2K (Tokai-to-Kamioka) Experiment is the first long-baseline neutrino superbeam oscillation experiment. The experiment directs the world's most intense neutrino beam from the J-PARC facility at Tokai village on the east coast of Japan, towards the Super-Kamiokande detector, located 295 km away in the mountains of western Japan. T2K made the world's first observation of the third neutrino mixing angle, called theta-1-3. The T2K experiment will measure the so-called atmospheric mixing angle to an accuracy of 1% and the atmospheric mass squared difference to an accuracy of 5%.
The experiment requires an excellent understanding of the properties of the neutrino beam and neutrino interactions. This is achieved with a suite of near detectors operating close to the source of the beam. The group leads the UK effort in the analysis of data from of one of the near detectors, analysis of neutrino interaction data, and measurement of neutrino oscillation parameters from T2K data.
The group is also a member of the Super-Kamiokande and Hyper-Kamiokande
collaborations.
