Query: ABM11 parton distributions and benchmarks   We present a determination of the nucleon parton distribution functions
(PDFs) and of the strong coupling constant $\alpha_s$ 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 $n_f=3,4,5$ and
uses the $\bar{MS}$ scheme for $\alpha_s$ 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.
