The CAD model of the PANDA Micro-Vertex-Detector in physics simulations
Abstract The Micro-Vertex-Detector (MVD) constitutes the inner tracker of the PANDA experiment, one of the large installations at the forthcoming FAIR facility. An optimization of the overall design has been accomplished. Currently the project is making rapid progress in hardware developments towards a finalized technical solution for the detector assembly. Therefore, suited tools are necessary to validate the impact of engineering solutions on the physics performance and to introduce a more realistic description of the detector. The cross-link between engineering developments and detector simulations is important for both further optimization of the detector assembly and appropriate implementation of the MVD into the PANDA simulation framework. In this article, a full chain of the migration of a detailed CAD model including all technical and engineering input to the software framework used for detector simulations and future data analysis of the PANDA experiment is presented. First, a short introduction to the experiment and a description of the conceptual layout is given. Afterward, the detailed MVD model and introduction to the physics simulation framework are described. Finally, first results of coverage tests performed and radiation length studies are exemplarily presented in order to demonstrate the successful migration of the entire detector model.

Beam tests and performance studies for the PANDA Micro-Vertex-Detector
The PANDA Micro-Vertex-Detector (MVD) will be the innermost tracker of the PANDA experiment and it will aim for the reconstruction of decay vertices of short-lived particles. The final geometry of the detector foresees both silicon strip and pixel sensors. A full characterization of the vertex reconstruction performance was realized with the PANDA simulation framework. Both systematic scans along the acceptance and the reconstruction of particle decays were performed. Beam tests of prototype sensors and front-end chips took place at several accelerators. Two independent beam telescopes, one equipped with silicon strip sensors, the other with silicon pixels, were tested simultaneously. An offline combined analysis was performed showing the feasibility of an event building on data coming from the two different systems.

Characterization of the PANDA Micro-Vertex-Detector and analysis of the first data measured with a tracking station
The Micro-Vertex-Detector (MVD) of the PANDA experiment has been studied and optimized making use of Monte Carlo simulations. A detailed geometry of active and passive components was implemented in the computing framework. This allows to perform an analysis of the geometrical coverage of the detector as well as of its material budget. The components of the MVD have been studied piece by piece and detailed material maps were produced. These results are crucial not only for the MVD, but for the overall PANDA detector because the MVD is the innermost detector of the experiment and it can have a large impact on the performance of outer ones. A tracking station composed of silicon strip detectors was designed, realized and tested in different beam setups. The simulation framework has been used as an interface to the real data coming from beam tests of this first prototype for the MVD. Energy calibration, alignment and analysis of the DAQ data have been performed.

The DSR-deformed relativistic symmetries and the relative locality of 3D quantum gravity
Over the last decade there were significant advances in the understanding of quantum gravity coupled to point particles in 3D ((2+1)-dimensional) spacetime. Most notably it is emerging that the theory can be effectively described as a theory of free particles on a momentum space with anti-deSitter geometry and with noncommutative spacetime coordinates of the type . We here show that the recently proposed relative-locality curved-momentum-space framework is ideally suited for accommodating these structures' characteristics of 3D quantum gravity. Through this we obtain an intuitive characterization of the DSR-deformed Poincare symmetries of 3D quantum gravity, and find that the associated relative spacetime locality is of the type producing dual-gravity lensing.
