000002401 520__ $$aAn analysis of the B+→K+νν decay mode using 63~fb−1 of Υ(4S) data collected during the 2019 and 2020ab run by the Belle II experiment is reported. A new inclusive tagging method is used to enhance sensitivity to this rare process. The method is validated with dedicated samples including 9.2 fb−1 of data taken off resonance.
