Y(5S)结果在Belle

Y(5S) Results at Belle

R. Louvot

摘要:

在KEKB B工厂(日本筑波)的Belle探测器在Y(5S)能量下记录的数据样本提供了关于Bs 0介子和Y(5S)共振的有趣和新的结果。最近的分析,基于在Y(5S)共振(23.6 /fb)或其附近(7.9 /fb)收集的数据样本,提出了一个特别关注的最终结果的Bs 0->Ds-π +和Bs 0-> Ds-/+ K+/-衰变,和有趣的Y(5S)-> Y(nS)π + π-测量。

英文摘要:

The data sample recorded with the Belle detector at the KEKB B factory (Tsukuba, Japan) operating at the Y(5S) energy provides interesting and new results about the Bs0 mesons and the Y(5S) resonance. Recent analyses, based on data samples collected at the Y(5S) resonance (23.6 /fb) or near it (7.9 /fb), are presented with a special focus on the final results on the Bs0 ->Ds- pi+ and Bs0 -> Ds-/+ K+/- decays, and on the intriguing Y(5S) -> Y(nS) pi+ pi- measurements.
