Abstract

n this paper, we report on the measurement of the rate of inclusive π0 [pi superscript 0] production induced by charged-current neutrino interactions in a C8H8 [C subscript 8 H subscript 8] target at a mean energy of 1.3 GeV in the K2K near detector. Out of a sample of 11 606 charged-current neutrino interactions, we select 479 π0 [pi superscript 0] events with two reconstructed photons. We find that the cross section for the inclusive π0 [pi superscript 0] production relative to the charged-current quasielastic cross section is σCCπ0/σCCQE=0.426±0.032 (stat)±0.035 (syst) [superscript delta CC pi superscript 0 / superscript delta CCQE = 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.
