Title: numu CC1pi+ Events Produced in the T2K Beam at Super-Kamiokande  

Abstract: T2K is an experiment designed to make precision measurements of neutrino oscillation parameters. Neutrinos produced in the Japan Proton Accelerator Complex are sent 295 km across Japan to the far detector Super-Kamiokande. Charged current quasi-elastic neutrino interactions in which the neutrino produces a lepton and a nucleon are dominant at T2K beam energies, and these are the signal events used in the measurement of muon disappearance parameters theta_23 and Delta m^2. The second most dominant neutrino interaction mode at T2K is the charged current single pion interaction (CC1pi+) in which both a lepton and a charged pion are produced in addition to the nucleon. This talk will present a method to identify charged pions and CC1pi+ neutrino interactions at Super-Kamiokande.  These are used to develop a selection of muon neutrino CC1pi+ interactions at Super-Kamiokande in the T2K beam, which is expected to increase the overall T2K statistics by 40%. Methods develope
 d to evaluate the systematic errors associated with explicitly selecting charged pions at Super-Kamiokande for the first time will also be discussed.
