Publication abstract: 

The PANDA experiment will study a wide range of physics topics with beams of antiprotons incident on fixed proton or complex nuclear targets. One issue is the Ds semileptonic decay, which is governed by the weak and strong forces. The interaction can be parameterized by a transition form factor. The performance of PANDA to measure the decay form factor of Ds + → νe η e+ is evaluated via Monte Carlo simulation. This thesis concentrates on describing the software development and the evaluation of the expected precision. A preliminary estimate of the expected count rate is obtained. In this measurement, it is essential to reconstruct the Ds semileptonic decay with high efficiency and purity in order to overcome the many orders of magnitude higher background. The Micro-Vertex-Detector plays an import role in the whole tracking system. The rate capability and tracking performance of the recent ASIC prototype for the readout of the MVD is tested using a beam of high-energy protons.
