The Belle II experiment is an upgrade of the B factory experiment Belle at the KEK laboratory in Tsukuba, Japan. It should record a 50 times larger data sample than the Belle experiment until 2022. With this one hopes to explain, among other questions, why the universe today consists only of matter and no anti-matter. Currently the detector and accelerator are upgraded. The expected large data sample also requires a new computing model to provide sufficient computing power and storage capacity for the processing and analysis of the data.




Contribution of the ETP

The ETP is engaged in the Belle II project since 2008 on the fields of software development, setup of the computing infrastructure, and construction of the pixel vertex detector. In particular we work as a leading institute on the track reconstruction in the central drift chamber, the software framework, the code management, and the event display. Further activities are the development of a database for calibration constants and the monitoring of grid sites.
