Semileptonic B Decays - Recent Results from LEP and Comparison with Upsilon(4S) Data
Abstract
Description
Recent analyses of the LEP and Upsilon(4S) data have better outlined the picture of semileptonic B decays. Results on inclusive and exclusive decay branching fractions and on the extraction of the |Vub| and |Vcb| elements of the CKM mixing matrix are discussed, together with some of the still open questions and the sources of model systematics.
