Abe, Francesca Bay, Silvestro Di Luise, Sosuke Horikawa, Sébastien Murphy, André Rubbia, et al.] Phys. rev. D. Open access ethresearch This paper presents a measurement of the charged current interaction rate of the electron neutrino beam component of the beam above 1.5 GeV using the large fiducial mass of the T2K π0 detector. The predominant portion of the νe flux (∼85%) at these energies comes from kaon decays. The measured ratio of the observed beam interaction rate to the predicted rate in the detector with water targets filled is 0.89±0.08(stat)±0.11(sys), and with the water targets emptied is 0.90±0.09(stat)±0.13 (sys). The ratio obtained for the interactions on water only from an event subtraction method is 0.87±0.33(stat)±0.21(sys). This is the first measurement of the interaction rate of electron neutrinos on water, which is particularly of interest to experiments with water Cherenkov detectors.
