Abstract
Proc. of DIS 2012, 407-412; DESY
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 $\overline{MS}$ 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.
