Description
We present a determination of the nucleon parton distribution functions (ABM11) and the strong coupling constant alpha_s at next-to-next-to-leading order (NNLO) in QCD based on world data for deep-inelastic scattering and fixed-target data for Drell-Yan process. The analysis is performed in the fixed-flavor number scheme for n_f=3,4,5 and uses the MSbar scheme for alpha_s and the heavy quark masses. The fit results are compared with other NNLO PDFs and used to compute the benchmark cross sections at hadron colliders to NNLO accuracy
