Description
A realistic calculation of the semileptonic decays of B-mesons, which depends in an essential manner on the Kobayashi-Maskawa matrix elements Vsub(b->c) and Vsub(b->u) only, is presented. A very good fit to the experimental lepton spectrum is obtained for vertical strokeVsub(b->u)/Vsub(b->c)vertical stroke2 = 0.10+-0.06, and from the world average for the B-lifetime (tausub(B) = 1.04+-0.15 ps), Vsub(b->c) = (5.9+-0.4)x10-2 and Vsub(b->u) = (1.9+-0.5)x10-2 are derived.
