A neural network z-vertex trigger for Belle II
We present the concept of a track trigger for the Belle II experiment, based on a neural network approach, that is able to reconstruct the z (longitudinal) position of the event vertex within the latency of the first level trigger. The trigger will thus be able to suppress a large fraction of the dominating background from events outside of the interaction region. The trigger uses the drift tim...

متن کاملThe Belle Silicon Vertex Detector
The silicon vertex detector of the Belle experiment has been built to provide the vertex information of B meson decays at the KEKB accelerator. It consists of three cylindrical layers of double sided, double metal silicon sensors read out by VA1 chips. The analog signals are transmitted to a system of fast analog-to-digital converters and are reduced on a system based on Motorola Digital Signal...
متن کاملA Novel Pixel Vertex Detector for the Belle II Experiment at SuperKEKB
At the KEK laboratory in Tsukuba, Japan, the upgrade of KEKB to “SuperKEKB” has started. Due to the much higher backgrounds expected at SuperKEKB, a massive upgrade of the Belle detector (“Belle II”) is in progress as well. For the innermost layers, close to the beam pipe, strip sensors will not work anymore due to the large occupancies, and a pixel detector becomes mandatory for Belle II. We r...
متن کاملA Level 1.5 Trigger for the Upgraded Belle SVD
An important conclusion of the Belle SVD/CDC Task Force is that the upgraded SVD should provide Level 1 trigger information. This information will be used to select events with z vertices close to the nominal IP. One way to accomplish this is to add discriminators to the VA chips, whose outputs could then be used to form a trigger signal. This approach is straightforward in principle, but invol...
