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