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