Discussion on implications for new physics

Abstract

The updated CLEO measurement of the electromagnetic penguin process $B \to X_s \gamma$ is presented and compared to the ALEPH result. Implications on new physics are discussed and the status of recent searches for $B \to X_s l^+ l^-$ modes is given.
