Update of the NNLO PDFs in the 3-, 4-, and 5-flavour scheme

Abstract

We report on an update of the next-to-next-to-leading order (NNLO) ABKM09 parton distributions functions. They are obtained with the use of the combined HERA collider Run I inclusive deep-inelastic scattering (DIS) data and the partial NNLO corrections to the heavy quark electro-production taken into account. The value of the strong couplig constant ${\alpha }_{\mathrm{s}}^{\mathrm{NNLO}}(M_{\mathrm{Z}})=0.1147(12)$ is obtained. The standard candle cross sections for the Tevatron collider and the LHC estimated with the updated PDFs are provided.

To appear in the proceedings of 18th International Workshop on Deep-Inelastic Scattering and Related Subjects (DIS 2010), Firenze, Italy, 19-23 Apr 2010
