Abstract

We discuss a possible interpretation of the scalar B-s0*(5725) and axial B-s1(5778) bottom-strange mesons as hadronic molecules-bound states of BK and B*K mesons, respectively. Using a phenomenological Lagrangian approach we analyze the strong B-s0*-> B-s pi(0), B-s1 -> B-s*pi(0) and the radiative B-s0*-> B-s*gamma, B-s1 -> B-s gamma, B-s1 -> B-s*gamma, B-s1 -> B-s0*gamma decays. We give predictions for the decay properties: effective couplings and decay widths.
