摘要:

在pi --> e nu衰变谱中寻找大量中微子的证据,背景pi --> mu --> e衰变链被高度抑制。上限(90% C.L.)中微子混合矩阵元|U_ei| ^2在中微子质量范围60- 129 MeV/c^2内的能级被设定为10^-8。

英文摘要:

Evidence of massive neutrinos in the pi --> e nu decay spectrum was sought with the background pi --> mu --> e decay chain highly suppressed. Upper limits (90% C.L.) on the neutrino mixing matrix element |U_ei|^2 in the neutrino mass region 60--129 MeV/c^2 were set at the level of 10^-8.
