Abstract
Using 226x10(6) B (B) over bar events recorded on the Gamma(4S) resonance with the BABAR detector at the SLAC e(+)e(-) PEP-II storage rings, we reconstruct B--> D(*0)e(-)(nu) over bar (e) decays using the decay chain D-*0 -> D-0 pi(0) and D-0 -> K-pi(+). From the dependence of their differential rate on w, the dot product of the four velocities of B- and D-*0, and using the form factor description by Caprini et al. with the parameters F(1) and rho(2)(A1), we obtain the results rho(2)(A1)=1.16 +/- 0.06 +/- 0.08, F(1)vertical bar V-cb vertical bar=(35.9 +/- 0.6 +/- 1.4) x 10(-3), and B(B--> D(*0)e(-)(nu) over bar (e)) = (5.56 +/- 0.08 +/- 0.41)%.
