Combinatorial Kalman Filter for the Belle II Experiment — Florian Bernlochner¹, Jochen Dingfelder¹, Alexander Glazov², Simon Kurz², and •Christian Wessel¹ for the Belle II collaboration — ¹Physikalisches Institut, Rheinische Friedrich-Wilhelms-Universität Bonn — ²Deutsches Elektronen-Synchrotron DESY

Kalman filters are a widely used tool in HEP to identify charged particle trajectories with a high efficiency and purity. The Belle II Combinatorial Kalman Filter (CKF) implementation is instrumental in achieving the physics goals of the experiment and is successfully being used in first emerging physics measurements. In this talk, I will summarize the key elements of the CKF implementation, show first results with data and give an outlook on future optimizations and extensions we have been working on.
