D0在Belle混合

D0 mixing at Belle

L. M. Zhang

摘要:

本文报道了最近在Belle实验室对D_0->K+K-/pi+pi-和D_0->K_S^0 pi+pi-衰变的D_0-D_0巴混合研究的两个结果。前者测量寿命y_{CP}的相对差异,给出D 0-D 0 bar混合的证据;后者测量D 0混合参数x和y。

英文摘要:

We report the recent two results of D0-D0bar mixing studies at Belle in D0->K+K-/pi+pi- and D0->K_S^0 pi+pi- decays. The former measures the relative difference of the lifetimes y_{CP}, giving the evidence of D0-D0bar mixing; the latter measures the D0 mixing parameters x and y.
