本文报道了MINOS实验基于质子对靶照射的跃迁搜索结果。我们在远探测器中观测到54个候选事件，并以近探测器中的测量结果为背景，要求在90% C. L时2sin <$2（2θ13）sin <$2 θ23<0.12（0.20）。对于正常（反向）体量层次，这个实验对正常中微子质量等级和最大sin θ 2（2θ23）的几乎所有的值都设定了最严格的限制。
This paper reports results from a search fortransitions by the MINOS experiment based on aprotons-on-target exposure. Our observation of 54 candidateevents in the far detector with a background ofevents predicted by the measurements in the near detector requires 2sin2(2θ13)sin2θ23<0.12(0.20) at the 90% C.L. for the normal (inverted) mass hierarchy at. The experiment sets the tightest limits to date on the value offor nearly all values offor the normal neutrino mass hierarchy and maximal sin2(2θ23).
