这封信报告了MINOS实验基于费米实验室NuMI束中3.14x10（20）质子靶上曝光的nu（mu）-> nu（e）跃迁的搜索。我们在远探测器中观察到35个事件，背景为27+/-5（stat）+/-2（syst）事件，这些事件是由近探测器中的测量预测的。如果用nu（mu）--> nu（e）振荡来解释，当|Δ m2| = 2.43 × 10（-3）eV 2和sin 2（2 θ（23））=1.0。
This Letter reports on a search for nu(mu) --> nu(e) transitions by the MINOS experiment based on a 3.14x10(20) protons-on-target exposure in the Fermilab NuMI beam. We observe 35 events in the Far Detector with a background of 27+/-5(stat)+/-2(syst) events predicted by the measurements in the Near Detector. If interpreted in terms of nu(mu) --> nu(e) oscillations, this 1.5sigma excess of events is consistent with sin2(2theta(13)) comparable to the CHOOZ limit when |Delta m2|=2.43x10(-3) eV2 and sin2(2theta(23))=1.0 are assumed.
