The CKM matrix element Î has been accurately determined at DELPHI. This has been possible by measuring moments of the hadronic mass distribution and of the lepton energy spectrum in inclusive B semileptonic decays, . In addition, production and decay properties of the most uncertain component of the hadronic system , namely the D ££ states, have been obtained. Results yield to some theoretical contradictions.doi:10.22323/1.021.0213 fatcat:3rozsuzafncero34zcca2fo6bq
