Improved measurement of neutral current coherent {pi}{sup 0} production on carbon in a few-GeV neutrino beam
2010
The SciBooNE Collaboration reports a measurement of neutral current coherent {pi}{sup 0} production on carbon by a muon neutrino beam with average energy 0.8 GeV. The separation of coherent from inclusive {pi}{sup 0} production has been improved by detecting recoil protons from resonant {pi}{sup 0} production. We measure the ratio of the neutral current coherent {pi}{sup 0} production to total charged current cross sections to be (1.16{+-}0.24)x10{sup -2}. The ratio of charged current coherent {pi}{sup +} to neutral current coherent {pi}{sup 0} production is calculated to be 0.14{sub -0.28}{sup +0.30}, using our published charged current coherent pion measurement.
