利用T2K离轴近探测器ND280首次测量了中微子带电流单正离子在水靶上产生的能量差分截面。在、和定义的受限相空间中，微分测量被表示为介子和介子运动学的函数。在受限相空间中测得水上的总磁通积分带电流单正子产生截面为⟨σ⟩ϕ=4.25±0.48(stat)±1.56(syst)×10-40 cm2/nucleon.总截面与Neut预测()一致，且低于精灵预测()。微分截面与Neut发生器符合得很好。精灵模拟很好地再现了分布的形状，但高估了总体横截面归一化。
The T2K off-axis near detector, ND280, is used to make the first differential cross section measurements of muon neutrino charged current single positive pion production on a water target at energies. The differential measurements are presented as a function of the muon and pion kinematics, in the restricted phase space defined by,,and. The total flux integratedcharged current single positive pion production cross section on water in the restricted phase space is measured to be ⟨σ⟩ϕ=4.25±0.48(stat)±1.56(syst)×10-40 cm2/nucleon. The total cross section is consistent with the NEUT prediction () andlower than the GENIE prediction (). The differential cross sections are in good agreement with the NEUT generator. The GENIE simulation reproduces well the shapes of the distributions, but overestimates the overall cross section normalization.
