在SciBooNE上寻找中微子带电电流相干π介子产生

Search for neutrino charged current coherent pion production at SciBooNE

K. Hiraide

摘要:

SciBooNE是一个中微子实验,测量1 GeV范围内碳上的中微子截面。我们研究了μ子中微子在碳原子\to μ 12 ^C π^+上散射产生的带电电流相干π介子。没有观察到相干π介子产生的证据。我们将平均中微子能量为1.1 GeV时带电电流相干π介子产生截面与总带电电流截面之比的90%置信度上限设为0.67 \times 10^{-2},平均中微子能量为2.2 GeV时为1.36 \times 10^{-2}。最后给出了最终数据样本的运动学分布。

英文摘要:

SciBooNE is a neutrino experiment measuring the neutrino cross sections on carbon in the one GeV region. We have performed a search for charged current coherent pion production from muon neutrinos scattering on carbon, ν_μ12^C \to μ12^C π^+. 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\times 10^{-2} at mean neutrino energy 1.1 GeV and 1.36 \times 10^{-2} at mean neutrino energy 2.2 GeV. The kinematic distributions of the final data sample are also presented.
