We present measurements of the first to fourth moments of the lepton mass squared q2 of B→Xcℓ¯νℓ decays for ℓ=e, μ and with Xc a hadronic system containing a charm quark. These results use a sample of electron-positron collisions at the Υ(4S) resonance corresponding to 62.8 fb−1 of integrated luminosity …
