Abstract
Semileptonic decays B --> D(-)l(+)nu X were selected from a sample of 3.1 million hadronic Z decays collected by the DELPHI detector at LEP . A topological search for semileptonic B decays to resonant and non-r esonant D(-)pi(+) states was performed and the ratio of the branching fractions: Br(B --> D(-)l(+)nu X)/Br(B --> D*(-)l(+)nu X) + Br(B-0 - -> D(-)l(+)nu) = 0.19 +/- 0.10(stat) +/- 0.06(syst) was determined. T aking into account this contribution, the differential decay width of B-0 --> D(-)l(+)nu was measured as a function of the momentum transfe r from the B to the D(-) in two separate analyses, using exclusive an d inclusive methods of D(-) reconstruction. The distributions were fi tted over the full momentum transfer range to extract the product of / V-cb/ times the normalization of the decay form factor F(q(max)(2)): F (q(max)(2))/V-cb/ = (35.4 +/- 1.9(stat) +/- 2.4(syst)) . 10(-3). The v alue of /V-cb/ was computed using theoretical calculations of F(q(max? 2), giving: /V-cb/ = (38.9 +/- 2.0(stat) +/- 2.6(syst) +/- 1.7(theory) ) . 10(-3). The total branching fraction Br(B-0 --> D(-)l(-)nu) was d etermined to be: Br(B-0 --> D(-)l(+)nu) = (5.52 +/- 0.17(stat) +/- 0. 68(syst))%.
