Heavy-flavor contributions at NNLO in CTEQ PDF analysis

Abstract

We discuss an NNLO realization of the general mass scheme S-ACOT-$\chi$ for treatment of heavy-flavour production in neutral current deep-inelastic scattering. Practical implementation of the NNLO calculation is illustrated on the example of semi-inclusive structure functions $F_{2c}(x,Q)$ and $F_{Lc}(x,Q)$.
