Abstract

We explore the transitions B(0+) to Bπ and Bs(0+) to BK from lattice QCD with Nf=2 flavors of sea quark, using the static approximation for the heavy quark. We evaluate the effective coupling constants, predicting a B(0+) to Bπ width of around 160 MeV. Our result for the coupling strength adds to the evidence that the Bs(0+) meson is not predominantly a molecular state (BK).
