Using the QCD sum rules technique we study several aspects of the phenomenology of the b-flavored strange meson B(s)0BAR. In particular, we evaluate the mass of the particle, the leptonic constant, and the form factors of the decays B(s)0BAR --> D(s)+l-v, B(s)0BAR --> D(s)*+l-vBAR, B(s)0BAR --> K*+l-vBAR. We also calculate, in the factorization approximation, a number of two-body nonleptonic B(s)0BAR decays. Finally, we compare our evaluation of the SU(3)F-breaking effects in the B(s)0BAR channel to other estimates.

Abstract

Using the QCD sum rules technique we study several aspects of the phenomenology of the b-flavored strange meson B(s)0BAR. In particular, we evaluate the mass of the particle, the leptonic constant, and the form factors of the decays B(s)0BAR --> D(s)+l-v, B(s)0BAR --> D(s)*+l-vBAR, B(s)0BAR --> K*+l-vBAR. We also calculate, in the factorization approximation, a number of two-body nonleptonic B(s)0BAR decays. Finally, we compare our evaluation of the SU(3)F-breaking effects in the B(s)0BAR channel to other estimates.
