Search for charged current coherent pion production on carbon in a few-GeV neutrino beam

The SciBooNE Collaboration has performed a search for charged current coherent pion production from muon neutrinos scattering on carbon, νυ ¹²C &8594; μ ¹²Cπ ⁺, with two distinct data samples. No evidence for coherent pion production is observed. We set 90% confidence level upper limits on the cross section ratio of charged current coherent pion production to the total charged current cross section at 0.67 x 10² at mean neutrino energy 1.1 GeV and 1.36 x 10² at mean neutrino energy 2.2 GeV.
