K/sup +/.衰变中介子的横向极化。——>π…一口0 /μ…/一口+ / . . nu . ./μ子……/在布鲁克海文国家实验室测量。已经检测和测量了2.1 x 10/sup 7/…/吃晚饭 +/..-->..e /一口+ / . . nu . ./sub - e/nu-bar/sub…我们发现垂直于K/sup +/衰变面P/sub n/的μ子极化的违反t分量= -0.0031 +- 0.0053。将这个结果与K/sub mu3//sup 0/的结果相结合,我们得到T-(因此CP-)不变性违反的度量Imxi = -0.010 +- 0.019。
The transverse polarization of muons from the decay K/sup +/..--> pi../sup 0/..mu../sup +/..nu../sub ..mu../ was measured at Brookhaven National Laboratory. Having detected and measured 2.1 x 10/sup 7/ ..mu../sup +/..-->..e/sup +/..nu../sub e/nu-bar/sub ..mu../ decays we found that the T-violating component of muon polarization perpendicular to the K/sup +/ decay plane P/sub n/ = -0.0031 +- 0.0053. Combining this result with our result for K/sub mu3//sup 0/, we obtain as a measure of T- (and therefore CP-) invariance violation Imxi = -0.010 +- 0.019.
