Description
Our exploratory study looks for direct access to the hadronic transition
amplitude at the resonance without resorting to the Lüscher formalism.
We study the decay $\Psi(3770)\to D\bar{D}$ by applying partially
twisted boundary conditions to the quenched charm quark,
circumventing possible problems with final state interactions.
If successful, we could compute the dependence of the transition amplitude
on the charm-quark mass, and test the predictions made by
phenomenological quark pair creation models.
Finally, we investigate if and to what extent an explicit extraction
of the excited state $\Psi(3770)$ with help of the GEVP is necessary for this analysis.
