Determination of |Vub|/|Vcb| with DELPHI at LEP
The DELPHI Collaboration, P. Abreu
The ratio of the CKM quark-mixing matrix elements |Vub|/|Vcb| has been measured using B hadron semileptonic decays. The analysis uses the reconstructed mass M_X of the secondary ha…
Measurement of the anti-B ---> D* pi lepton anti-neutrino(lepton) Branching Fraction
The DELPHI Collaboration, P. Abreu
A study of b semileptonic decays into D, D pi+- and D* pi+- final states is presented. The D0, D+ and D*+ mesons are exclusively reconstructed in Z decay data recorded from 1992 to…
Rapidity-Rank Structure of p pbar Pairs in Hadronic Z0 Decays
The DELPHI Collaboration, P. Abreu
The rapidity-rank structure of p pbar pairs is used to analyze the mechanism of baryon production in hadronic Z0 decay. The relative occurrence of the rapidity-ordered configuratio…
