Event Details & Abstract: 

The T2K (Tokai to Kamioka) experiment is a long baseline neutrino oscillation experiment where a narrow band (by energy) neutrino beam of primarily muon neutrinos or muon anti-neutrinos is produced in Tokai and directed towards Kamioka in Japan. The neutrinos in the beam are first detected at the T2K near detector complex 280m from the beam source (ND280) and then travel 295km before being detected again at the Super-Kamiokande (Super-K) water-Cherenkov detector. In addition to measuring the flux of neutrinos in the T2K beamline en route to Super-K, other physics analyses are performed at ND280. This talk describes one such measurement where the Pi-Zero Detector (P0D) and a time projection chamber at ND280 were used to measure the charged current cross section for muon anti-neutrinos with water as the interaction target and no pions in the final state. Such a measurement is a T2K and world first. This cross section was measured differentially by the outgoing lepton true kinematics using a recently developed at T2K binned likelihood fitting framework.
