MEASUREMENT OF THE DECAY B- -] D(STAR0)L(-)NU-BAR

Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we have studied the decay B- --> D*0l-nuBAR, where l- = e- or mu-, using the D(0)gamma and D(0)pi(0) decay modes of the D*0 meson. B mesons were produced in 209 000 decays of UPSILON (4S). Assuming electron-muon universality, we...

Zusammenfassung:Using the ARGUS detector at the e+e- storage ring DORIS II at DESY, we have studied the decay B- --> D*0l-nuBAR, where l- = e- or mu-, using the D(0)gamma and D(0)pi(0) decay modes of the D*0 meson. B mesons were produced in 209 000 decays of UPSILON (4S). Assuming electron-muon universality, we obtain a value for the branching ratio of BR(B- --> D*0l-nuBAR) = (5.8 +/- 1.4 +/- 1.3)%.
