Abstract

An analysis technique for isolating neutrino interactions on hydrogen, from a target containing a mixture of different nuclei, would provide numerous benefits. Namely, hydrogen is free of nuclear effects and enables better reconstruction of the neutrino energy spectra; key for neutrino oscillation experiments. Presented using Monte Carlo simulations of the ND280 near detector is the status of such a measurement on v-H resonance production by the T2K experiment.
