Abstract

We present a determination of the nucleon parton distribution functions (PDFs) and of the strong coupling constant αs\alpha_s at next-to-next-to-leading order (NNLO) in QCD based on the world data for deep-inelastic scattering and the fixed-target data for the Drell-Yan process. The analysis is performed in the fixed-flavor number scheme for nf=3,4,5n_f=3,4,5 and uses the MSˉ\bar{MS} scheme for αs\alpha_s and the heavy quark masses. The fit results are compared with other PDFs and used to compute the benchmark cross sections at hadron colliders to the NNLO accuracy.
