摘要：This paper is a review of measurement of the CP-violating phase f J/yf s and the decay width difference for the two mass eigenstates DGs from flavor-tagged decay B0s →J/yf : DGs = 0.19±0.07 (stat) +0.02 −0.01 (syst) ps−1, f J/yf s = −0.57+0.24 −0.30 (stat) +0.07 −0.02 (syst). The allowed 90% C.L. intervals of DGs and fs are 0.06
