The J=ÃDD¤ Vertex
We employ QCD sum rules to calculate the J=ÃDD¤ form factors and coupling constant by studying the threepointJ=ÃD¤D correlation function. We find that the momentum dependence of the form factor depends onthe off-shell meson. We get a value for the coupling which is in agreement with estimates based...
