Tuning of the cluster selection of the Belle II Pixel Vertex Detector

The main task of the tracking is the reconstruction of charged particles originating from primary and secondary vertices. Due to the present implementation of the tracking algorithms it is not possible to use the reconstructed hits of the first layer of the Pixel Vertex Detector when no hits are available in the second layer, because of the impact of the high machine background on the first layer. The task is the development of an algorithm for improving the separation power between the clusters coming from interesting tracks and the ones coming from the machine background.
