## Abstract

In this paper we report on the measurement of the rate of inclusive $\\pi^0$ production induced by charged-current neutrino interactions in a C$\_8$H$\_8$ 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 $\\pi^0$ events with two reconstructed photons. We find that the cross section for the inclusive $\\pi^0$ production relative to the charged-current quasi-elastic cross section is $$\\frac{\\sigma\_{CC\\pi^0}}{\\sigma\_{CCQE}}=0.426\\pm0.032(stat.)\\pm0.035(syst.)$$ The energy dependent cross section ratio is also measured. The results are consistent with previous experiments for exclusive channels on different targets.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
