Abstract

In this paper we report on the measurement of the rate of inclusive π0\pi^0 production induced by charged-current neutrino interactions in a C8_8H8_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^0 events with two reconstructed photons. We find that the cross section for the inclusive π0\pi^0 production relative to the charged-current quasi-elastic cross section is \fracσ_CCπ⁰σ_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.
