Abstract

In this paper, we report on the measurement of the rate of inclusive π0 production induced by charged-current neutrino interactions in a C 8H8 target at a mean energy of 1.3 GeV in the K2K near detector. Out of a sample of 11606 charged-current neutrino interactions, we select 479 π0 events with two reconstructed photons. We find that the cross section for the inclusive π0 production relative to the charged-current quasielastic cross section is σCCπ0σCCQE=0. 426±0.032(stat)±0.035(syst). The energy-dependent cross section ratio is also measured. The results are consistent with previous experiments for exclusive channels on different targets.
