摘要:

总截面是当前和未来中微子振荡实验的重要组成部分。我们提出了测量的总带电电流中微子和反中微子截面闪烁体(CH)在NuMI低能量束线使用{ \em原位}预测的形状作为中微子能量的函数从2- 50 GeV的通量。这种通量预测利用了这样一个事实,即中微子和反中微子相互作用与低核反冲能($ν$)有一个几乎恒定的截面作为入射中微子能量的函数。该测量是低$ν$通量技术的最低能量应用,首次用于NuMI反中微子束配置,并表明该技术适用于未来以多GeV能量运行的中微子束。所提出的截面测量值是迄今为止低于5 GeV的最精确的测量值。

英文摘要:

The total cross sections are important ingredients for the current and future neutrino oscillation experiments. We present measurements of the total charged-current neutrino and antineutrino cross sections on scintillator (CH) in the NuMI low-energy beamline using an {\em in situ} prediction of the shape of the flux as a function of neutrino energy from 2--50 GeV. This flux prediction takes advantage of the fact that neutrino and antineutrino interactions with low nuclear recoil energy ($ν$) have a nearly constant cross section as a function of incident neutrino energy. This measurement is the lowest energy application of the low-$ν$ flux technique, the first time it has been used in the NuMI antineutrino beam configuration, and demonstrates that the technique is applicable to future neutrino beams operating at multi-GeV energies. The cross section measurements presented are the most precise measurements to date below 5 GeV.
