在NOMAD实验中收集的νμ带电电流事件中搜索反应：[公式：见文]提取了由35个事件组成的高纯度D★+样品。测定了νμ带电电流相互作用的D★+产率为T=(0.79±0.17（stat.）±0.10(syst.))%。D★+吸收的强子射流能量的平均分数为0.67±0.02（stat.）±0.02（syst.）。给出了D★+的破碎变量z、pt2和xf的分布。
A search was made among νμcharged current events collected in the NOMAD experiment for the reaction: [Formula: see text] A high purity D★+sample composed of 35 events was extracted. The D★+yield in νμcharged current interactions was measured to be T=(0.79±0.17(stat.)±0.10(syst.))%. The mean fraction of the hadronic jet energy taken by the D★+is 0.67±0.02(stat.)±0.02(syst.). The distributions of the fragmentation variables z, PT2and xFfor D★+are also presented.
