我们报道了在东海-神冈实验中对诱导的相干带电介子产生截面的最新测量，以及对原子核上诱导的相干带电介子产生截面的首次测量。这是在最终状态相空间的一个限制区域内测量的，并且在使用T2K近探测器的平均（反）中微子能量为0.85 GeV。测量到的带电电流相干介子产生通量平均截面为(2.98±0.37（stat）±0.31（syst)-0.00+0.49（Q2模型））×10-40 cm2。新的诱导截面测量值为(3.05±0.71（stat）±0.39（syst)-0.00+0.74（Q2模型））×10-40 cm2。结果与NEUT 5.4.0 Berger-Sehgal（2009）和GENIE 2.8.0 Rein-Sehgal（2007）模型预测兼容。
We report an updated measurement of the-induced, and the first measurement of the-induced coherent charged pion production cross section onnuclei in the Tokai-to-Kamioka experiment. This is measured in a restricted region of the final-state phase space for which,and, and at a mean (anti)neutrino energy of 0.85 GeV using the T2K near detector. The measuredcharged current coherent pion production flux-averaged cross section onis (2.98±0.37(stat)±0.31(syst)-0.00+0.49(Q2 model))×10-40 cm2. The new measurement of the-induced cross section onis (3.05±0.71(stat)±0.39(syst)-0.00+0.74(Q2 model))×10-40 cm2. The results are compatible with both the NEUT 5.4.0 Berger-Sehgal (2009) and GENIE 2.8.0 Rein-Sehgal (2007) model predictions.
