【 摘 要 】

We report on software development to evaluate the expected performance of the PANDA detector to measure the semileptonic form factor Ds→ e + v + π, η,η'. The related decay models in this chain are checked via a Dalitz plot analysis; the present version of EvtGen in PandaRoot has been enhanced by a new model describing the Ds→ KKπ decay. With the help of theoretical predictions of the cross section, the expected count rate is estimated.
