The T2K Experiment


Abstract in English

The T2K experiment is a long-baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle {theta}_{13} by observing { u}_e appearance in a { u}_{mu} beam. It also aims to make a precision measurement of the known oscillation parameters, {Delta}m^{2}_{23} and sin^{2} 2{theta}_{23}, via { u}_{mu} disappearance studies. Other goals of the experiment include various neutrino cross section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem.
