The $\bar PANDA$ experiment at FAIR (Facility for Antiproton and IonResearch) in Darmstadt (Germany) is designed for $\bar p p$ annihilationstudies and it will investigate fundamental questions of hadron and nuclearphysics in interactions of antiprotons with nucleons and nuclei. Gluonicexcitations and the physics of hadrons with strange and charm quarks will beaccessible with unprecedented accuracy, thereby allowing high precision testsof the strong interactions. In particular, the $D_{s0}^*(2317)^+$ and$D_{s1}(2460)^+$ are still of high interest 11 years after their discovery,because they can not be simply understood in term of potential models. Theavailable statistics and resolution of the past experiments did not allow toclarify their nature. Recently LHCb at CERN has made progresses in thisrespect, but still not at the level of precision required in order to clarifythe puzzle of the $cs$-spectrum. $\bar PANDA$ will be able to achieve a factor20 higher mass resolution than attained at the B-factories, which is expectedto be decisive on these and second-order open questions. The technique toevaluate the width from the excitation function of the cross section of the$D_s$ mesons will be presented, and ongoing simulations performed with$PandaRoot$ will be shown.
