Hadronic mass moments in inclusive semileptonic B meson decays.

We have measured the first and second moments of the hadronic mass-squared distribution in B-->X(c)l nu, for P(lepton)>1.5 GeV/c. We find <m(2)(x)-m macro(2)(d)=""> = 0.251+/-0.066 GeV(2), <(M(2)(X)-<m(2)(x)>)(2)> = 0.576+/-0.170 GeV(4), where M macr...
