QCD Sum Rules for the production of the X(3872) as a mixed molecule-charmonium state in B meson decay

C. M. Zanetti, M. Nielsen, R. D. Matheus

We use QCD sum rules to calculate the branching ratio for the production of the meson X(3872) in the decay $B\to X(3872)K$, assumed to be a mixture between charmonium and exotic mo…
