Abstract
We present a determination of parton distribution functions (ABM11) and the strong coupling constant at next-to-leading order and next-to-next-to-leading order (NNLO) in QCD based on world data for deep-inelastic scattering and fixed-target data for the Drell-Yan process. The analysis is performed in the fixed-flavor number scheme for , 4, 5 and uses the scheme for and the heavy-quark masses. At NNLO we obtain the value . The fit results are used to compute benchmark cross sections at hadron colliders to NNLO accuracy and to compare to data from the LHC.
