Abstract

We report the first evidence of charmless semileptonic decays of B mesons. In the momentum interval 2.42.6 GeV/c where the background from bcl is negligible, the average of the measured ue and u partial branching ratios is Bub(2.4,2.6) =(1.80.40.3)×10-4. Inclusion of data from the interval 2.22.4 GeV/c, where the lepton yield is dominated by bcl, gives Bub(2.2,2.6) =(3.30.80.8)×10-4. Vub/Vcb depends on the theoretical model of bul decay and is approximately 0.1.
