Y(5S)和B_s衰变

Y(5S) and B_s decays at Belle

A. Drutskoy

摘要:

本文讨论了利用KEKB非对称能量e+ e对撞机Belle探测器在Y(5S)共振上收集的23.6 fb^-1数据样本所获得的最新结果。报道了几种B_s^0衰变分支分数的测量结果。本文讨论了Y(5S)衰变到B^+和B^0介子或底鎓态通道的研究。

英文摘要:

Recent results obtained using the data sample of 23.6 fb^-1 collected on the Y(5S) resonance with the Belle detector at the KEKB asymmetric energy e+ e- collider are discussed. Measurements of several B_s^0 decay branching fractions are reported. Studies of the Y(5S) decays to the channels with B^+ and B^0 mesons or bottomonium states are discussed.
