Abstract
We report a measurement of the Cabibbo-Kobayashi-Maskawa matrix elemen t \V-cb\. From approximately 4.2 million hadronic Z(O) decays recorded with the OPAL detector, a sample is selected containing 1251 +/- 125 (B) over bar(0) --> D+ l(--)nu- xi candidates, where l is either an e lectron or a muon, Using Heavy Quark Effective Theory calculations for the decay form factor at zero recoil of the D+ meson in the (B) over bar(0) rest frame, we derive \V-cb\ = [36.0 +/- 2.1 (stat) +/- 2.4 (s yst) +/- 1.2 (theory)] x 10(-3).
