Publication abstract: 

At the facility FAIR, now under construction as an extension of the GSI Laboratory, the PANDA experiment will play an important rule for the understanding of the strong interaction at intermediate energies. The PANDA apparatus is designed to allow a precise reconstruction of particles momenta and decay vertices; in this context the innermost tracker, the Micro Vertex Detector will play a fundamental rule. Looking forward for the PANDA detector system, which shall operate in a selftriggering acquisition mode, the rst hybrid pixel prototypes were tested and a rst version of a triggerless data-managing framework was implemented. The experimental results obtained in two di erent beam tests will be presented. Detailed MonteCarlo study of the pbarp->psi(4040) D*+ D*- decay chain were performed to test the potential reconstruction performance, the secondary vertices reconstruction capability and the hadronic background suppression.
