We analyze nonleptonic B{sub s} decays to a charmonium state and a light meson, induced by the b{yields}ccs transition, which are useful to access the B{sub s}-B{sub s} mixing phase {beta}{sub s}. We use generalized factorization and SU(3){sub F} symmetry to relate such modes to correspondent B decay channels. We discuss the feasibility of the measurements in the various channels, stressing the importance of comparing different determinations of {beta}{sub s} in view of the hints of new physics effects recently emerged in the B{sub s} sector. Finally, adopting a general parametrization of new physics contributions to the decay amplitudes, we discuss how to experimentally constrain new physics parameters.
