Description
The Belle II experiment has been taking data at the SuperKEKB collider since 2018. Particle identification is a key component of the reconstruction, and several detector upgrades from Belle to Belle II were designed to maintain performance with the higher background rates.
We present a method for a data-driven calibration that improves the overall particle identification performance and is resilient against imperfections in the calibration of individual detectors. Our framework also defines a “blame” metric that identifies the detectors with largest contributions to correctly and incorrectly assigned particle hypotheses.
