摘要：

The strange B meson B-s = <(b)over bar s> and its charge-conjugate <(B)over bar (s)> = <b(S) over bar> are expected to mix with one another in such a way that the mass eigenstates B-s(H) (''heavy'') and B-s(L) (''light'') may have a perceptible lifetime difference of up to 40%, with the CP-even eigenstate being shorter-lived. A simple transversity analysis permits one to separate the CP-even and CP-odd components of B-s --> J/psi phi, and thus to determine the lifetime difference. The utility of a similar analysis for B-0 --> J/psi K-*0 is noted.
