摘要：

New rate measurements of B-0 decays into pi(0)pi(0), pi(0)eta, pi(0)eta('), eta eta, eta eta('), eta(')eta(') and K+K- are used in conjunction with flavor SU(3) to constrain the coefficients S and C of sin Delta mt and cos Delta mt in the time-dependent CP asymmetries of B-0 ->eta K-'(S) and B-0 ->pi K-0(S). Experimental values of (S eta K)-K-' are now seen to be closer to the Standard Model expectations, fully consistent with the new improved bounds.
