Updates on the Micro Vertex Detector Geometry for the CBM - Experiment — •Philipp Sitzmann for the CBM-MVD collaboration — Goethe-Universität Frankfurt

The Compressed Baryonic Matter experiment at FAIR (CBM) is a dedicated fix-target experiment design to explore the QCD phase diagram in the region of high net-baryon density. The CBM Micro Vertex Detector employs CMOS Monolithic Active Pixel Sensors. A new sensor generation called MIMOSIS is under development at IPHC Strasbourg.
The stations of the MVD had to be adapted to the needs of the now larger sensors. In the ongoing development, two dedicated geometry setups of the MVD have been implemented: one optimized for secondary vertex reconstruction for open charm measurements and another one suited for multi-strange hyperon tracking. The neccessary updates in the geometry and the results in vertexing and track reconstruction will be discussed. Furthermore, a short overview on the MVD software as part of the CBM-ROOT framework will be given, highlighting the flexibility to include new geometries in the software.

This work has been supported by BMBF (05P15RFFC1), GSI, HIC for FAIR and HGS-HIRe.
