Parton distribution functions from the precise NNLO QCD fit
PACS: 06.20.Jr, 12.38.Bx, 13.60.Hb
Abstract
We report the parton distribution functions (PDFs) determined from the NNLO QCD analysis of the world inclusive DIS data with account of the precise NNLO QCD corrections to the evolution equations kernel. The value of strong coupling constant \alpha^{\rm NNLO}_{\rm s}(M_{\rm Z})=0.1141\pm 0.0014({\rm exp.}), in fair agreement with one obtained using the earlier approximate NNLO kernel by van Neerven-Vogt. The intermediate bosons rates calculated in the NNLO using obtained PDFs are in agreement to the latest Run II results.
