Strategy for studying νμ CCQE interactions in the T2K near detector

The T2K (Tokai‐to‐Kamioka) experiment[1, 2] is a long‐baseline neutrino oscillation experiment, currently operating in Japan, aiming at measuring the θ13 mixing angle. It uses an intense off‐axis beam of mainly muon neutrinos incident on the Super‐Kamiokande detector[5]. The off‐axis near detector complex, ND280[2], can be used to perform charge current quasi‐elastic (CCQE) measurements, that define the flux normalization and predict the unoscillated spectrum. The strategy for studying νμ CCQE interactions in the ND280 detector is described, together with the first inclusive charge current results from the first period of T2K operation.
