摘要

我们讨论了从BdDKS(L)B_d\to DK_{S(L)}BsDη(),Dϕ,...B_s\to D\eta^{(')}, D\phi, ...衰变中确定幺正三角形角度γ\gamma的新的、理论上干净的策略,并指出BsDKS(L)B_s\to DK_{S(L)}BdDπ0,Dρ0,...B_d\to D\pi^0, D\rho^0, ...模式分别允许对Bq0B^0_q--Bq0ˉ\bar{B^0_q}混合相位ϕs\phi_sϕd\phi_d进行非常有趣的测定。它们的颜色允许对应模式BsDs()±K,...B_s\to D_s^{(*)\pm} K^\mp, ...BdD()±π,...B_d\to D^{(*)\pm} \pi^\mp, ...也为探测γ\gamma提供了新方法。
