SciBooNE协作组利用两个不同的数据样本，对μ子中微子在碳上散射产生的带电电流相干π介子进行了搜索，nu{sub {mu}}{sup 12}C- {yields} {mu}{sup 12}CPI{sup +}。没有观察到相干π介子产生的证据。我们设定了90%置信水平的上限为0.67 × 10{sup-2}在平均中微子能量为1.1 GeV和1.36 × 10{sup-2}在平均中微子能量为2.2 GeV的带电电流相干π介子生产的截面比的总带电电流截面。
The SciBooNE Collaboration has performed a search for charged current coherent pion production from muon neutrinos scattering on carbon, nu{sub {mu}}{sup 12}C- {yields} {mu}{sup 12}Cpi{sup +}, 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 10{sup -2} at mean neutrino energy 1.1 GeV and 1.36 x 10{sup -2} at mean neutrino energy 2.2 GeV.
