摘要:

SciBooNE协作报告了使用费米实验室助推器中微子束测量μ子中微子在碳上的平均能量为0.8 GeV的包容性带电电流相互作用。我们比较我们的测量与两个中微子相互作用模拟:NEUT和NUANCE。通过拟合μ子运动学,提取了带电电流相互作用率(通量与截面的乘积),能量相关分析的精度为6-15%,能量积分分析的精度为3%。我们还从观测到的速率中提取了CC包含的相互作用截面,能量依赖分析的精度为10-30%,能量综合分析的精度为8%。这是第一次测量的CC包容截面的碳约1 GeV。这些结果可用于将先前的SciBooNE截面比测量值转换为绝对截面值。

英文摘要:

The SciBooNE Collaboration reports a measurement of inclusive charged current interactions of muon neutrinos on carbon with an average energy of 0.8 GeV using the Fermilab Booster Neutrino Beam. We compare our measurement with two neutrino interaction simulations: NEUT and NUANCE. The charged current interaction rates (product of flux and cross section) are extracted by fitting the muon kinematics, with a precision of 6-15% for the energy dependent and 3% for the energy integrated analyses. We also extract CC inclusive interaction cross sections from the observed rates, with a precision of 10-30% for the energy dependent and 8% for the energy integrated analyses. This is the first measurement of the CC inclusive cross section on carbon around 1 GeV. These results can be used to convert previous SciBooNE cross section ratio measurements to absolute cross section values.
