Abstract

We estimate the heavy quark effective theory parameter λ1 from the inclusive semileptonic B-meson decay spectrum. By using recent CLEO double lepton tagging data of B→Xeν, which show the lepton momentum as low as 0.6 GeV, we extracted λ1∼-0.58 GeV2. We also derived Λ̄∼0.46 GeV and |Vcb|=0.041±0.002.
