Meson Loops and the gDD Coupling
The D∗Dπ form factor is evaluated at low and moderate Q2 in a hadronic loop model, for off-shell D mesons.The results contain arbitrary constants, which are fixed so as to match a previous QCD sum rule calculationvalid at higher Q2. The form factor obtained in this way is used to extract...
