Simulations on the measurement of the Ds meson semileptonic form factor with the PANDA detector

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.
