| dc.description.abstract | Using the CLEO II detector and a sample of 955 000 UPSILON(4S) decays we have confirmed charmless semileptonic decays of B mesons. In the momentum interval 2.3-2.6 GeV/c we observe an excess of 107 +/- 15 +/- 11 leptons, which we attribute to b --> ulnu. This result yields a model-dependent range of values for \V(ub)/V(cb)\ that is lower than has been obtained in previous studies. For the inclusive spectator model of Altarelli et al. we find \V(ub)/V(cb)\ = 0.076 +/- 0.008. Models that describe b --> ulnu with a limited set of exclusive final states give \V(ub)/V(cb)\ = 0.06 - 0.10. | |
