Previously published CTEQ6 parton distributions adopt the conventional zero-mass parton scheme; these sets are most appropriate for use with massless hard-scattering matrix elements commonly found in most physics applications. For precision observables which are sensitive to charm and bottom quark mass effects, we provide in this paper an additional CTEQ6HQ parton distribution set determined in the more general variable flavor number scheme which incorporates heavy flavor mass effects.

QCD formulation of charm production in deep-inelastic scattering and the sea-quark-gluon dichotomy.
Gluon-initiated contributions to deep-inelastic-scattering processes, such as charm production, can be comparable in magnitude to the leading-order'' sea-quark processes, which implies that previous analyses of charm-production data to extract the strange and charm content of the nucleon need to be reassessed.
