000002935 520__ $$aIn this thesis a novel hybrid approach to tag-side reconstruction is presented, where the tag-side is only partially reconstructed in order to improve the purity compared to the inclusive tagging, while retaining a high efficiency. In a second part of the thesis a new feature is added to the Full Event Interpretation to remove background from e + e − → q q̄ (q = u, d, c, s) events, which is an important background for many Belle II analyses. The discrimination between e + e − → Υ(4S) and e + e − → q q̄ events can be achieved by exploiting the different event kinematics.
