CP-violating asymmetries in charmless nonleptonic decays B -> PP, PV, VV in the factorization approach - art. no. 014005

We present estimates of the direct (in decay amplitudes) and indirect (mixi ng-induced) CP-violating asymmetries in the nonleptonic charmless two-body decay rates for B --> PP, B --> PV, and B --> VV decays and their charged c onjugates, where P(V) is a Light pseudoscalar (vector) mason. These estimat es are based on a generalized factorization approach making use of next-to- leading order perturbative QCD contributions which generate the required st rong phases. No soft final state interactions are included. We study the de pendence of the asymmetries on a number of input parameters and show that t here are at least two (possibly three) classes of decays in which the asymm etries are parametrically stable in this approach. The decay modes of parti cular interest are [GRAPHICS] [GRAPHICS] [GRAPHICS] [GRAPHICS] and [GRAPHICS] Likewise, the CP-violating asymmetry in the decays [GRAPHICS] with h(0) = pi(0), K-S(0), eta, eta' is found to be parametrically stable a nd large. Measurements of these asymmetries will lead to a determination of the phases sin 2 alpha and sin 2 beta and we work out the relationships in these modes in the present theoretical framework. We also show the extent of the so-called "penguin pollution" in the rate asymmetry A(CP) (pi(+)pi(- )) and of the ''tree shadow'' in the asymmetry A(CP)(K(S)(0)eta') which wil l effect the determination of sin 2 alpha and sin 2 beta from the respectiv e measurements. CP-violating asymmetries in B+/- decays depend on a model p arameter in the penguin amplitudes and theoretical predictions require furt her experimental or theoretical input. Of these, CP-violating asymmetries i n B+/- --> pi(+)/- eta', B+/- --> K*(+/-) eta, B+/- --> K*(+/-) eta', and B +/- --> K*(+/-) rho(0) are potentially interesting and are studied here.
