Abstract: In the physics part of the thesis, the exotic state X(4014) is studied for Belle II. A bound state of two mesons is interacting via one-pion exchange. As a consequence of heavy quark spin symmetry, those states would have partner states with higher mass and total angular momentum (J). In case of the X(3872), which is close to the D∗0 ̄D0 threshold, the predicted partner resonance is predicted near the D∗0 ̄D∗0 threshold. In this thesis, a simulation of this resonance is performed on Belle II Monte Carlo and the discovery potential for various different width and branching fraction scenarios is estimated. In the technical part of the thesis a taskj of the Belle II PXD data qcquisition system is studie, i.e. if 32 optical links from the DHH system to the ONSEN system can be reduced to one single optical link with 10G bandwidth.
