Findings

Improved B flavor tagging techniques.

Observation of doubly charmed B decays.

Enhanced measurement precision of B decay parameters.

Abstract

This contribution concerns three contributed papers that share the common feature of analysing fully- (or almost fully-) reconstructed B decays coming from a sample of four million hadronic Z decays collected with the ALEPH detector at LEP...
