Description

The KDS*D form factor is evaluated in a QCD sum rule calculation using a three point function. We have also estimated the KDS*D coupling constant. For these purpose we have computed the form factors momentum dependence in the cases where the K is off-shell, the DS* is off-shell and introduce also the case of D off-shell. We conclude that this momentum dependence is very different but they lead the same coupling constant. (author)
