We present GFlaT, a new algorithm that uses a graph-neural-network to determine the flavor of neutral \(B\) mesons produced in \(\Upsilon(4S)\) decays. It improves previous algorithms by using the information from all charged final-state particles and the relations between them. We evaluate its performance using \(B\) decays to flavor-specific hadr...
