Abstract

The first and second moments of the hadronic mass-squared distribution in the B meson semileptonic decay to charm, B → X ℓ ν, were measured. The measurement of and the heavy quark effective theory expression for this moment were used, in conjunction with similar information on the first moment of the photon energy spectrum in B → s . As a result, λ and ∧̄ were determined. c X D λ 2 2
