Search for B→ K^(*)νν at the Belle II experiment with machine learning techniques — •Cyrille Praz — Deutsches Elektronen-Synchrotron (DESY), Hamburg, Germany

The Belle II experiment, located in Tsukuba, Japan along the SuperKEKB e⁺e⁻ collider, has started to collect data in 2018 and offers many opportunities to improve our understanding of the B-meson decays. In particular, the B→ K^(*)νν decay has not been observed yet, it can be computed with accuracy in the Standard Model and is sensitive to new physics models. This presentation gives a brief overview of a novel approach to search for this decay and focuses on the machine learning techniques that are used to reject the background and select the signal.
