Description
In this work, we evaluate the coupling constant and the form factors of the vertex J/ψDs using the techniques of the QCD sum rules. We consider all the three mesons off shell, resulting in three different form factors. However, despite the different form factors, when extrapolated to the pole of each off-shell meson, we find coupling constants that are in completely agreement each other. The result for the vertex J/ψDs coupling constant is gJ/ψD*sDs =4.30+0.42 −0.37GeV−1. (paper)
