Kavli Affiliate: T. Higuchi | First 5 Authors: F. Abudinén, N. Akopov, A. Aloisio, V. Babu, Sw. Banerjee | Summary: We report on new flavor-tagging algorithms developed to determine the quark-flavor content of bottom ($B$) mesons at Belle II. The algorithms provide essential inputs for measurements of quark-flavor mixing and charge-parity violation. We validate and […]
