Popis
Shrnutí:The first and second moments of the hadronic mass-squared distribution in the B meson semileptonic decay to charm, B → X c ℓ ν, were measured. The measurement of <m -="" 2="" d="" m̄="" x=""> 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 λ. As a result, λ and ∧̄ were determined.</m>
