我们报告搜索和衰变，光子的能量需要大于0.5 GeV。这些结果是在KEKB对撞机上用贝儿探测器从近4S共振处收集的含有对的样品中获得的。我们没有观察到显着的信号，无论是衰变和设置上限的分支分数在90%的置信水平。
We report searches foranddecays, where the energy of the photon is required to be larger than 0.5 GeV. These results are obtained from adata sample that containspairs and was collected near the ϒ(4S) resonance with the Belle detector at the KEKBcollider. We observe no significant signal for either decay and set upper limits on their branching fractions at 90% confidence level ofand.
