本文利用KEKB非对称能量对撞机上的贝儿探测器记录的个对的完整数据样本,对轻子味违反衰变进行了研究。我们使用的事件中,一个子是完全重建的强子衰变模式。利用重建的轻子的动量和信号衰变产生的轻子的动量间接重建轻子。我们没有发现衰变的证据,并在90%的置信水平下对它们的分支分数设定了上限。
We present a search for the lepton-flavor-violating decays, where, using the full data sample ofpairs recorded by the Belle detector at the KEKB asymmetric-energycollider. We use events in which onemeson is fully reconstructed in a hadronic decay mode. Thelepton is reconstructed indirectly using the momentum of the reconstructedand that of thefrom the signal decay. We find no evidence fordecays and set upper limits on their branching fractions at 90% confidence level ofand.
