We report an updated version of the ABKM09 NNLO PDF fit, which includes the most recent HERA collider data on the inclusive cross sections and an improved treatment of the heavy-quark contribution to deep-inelastic scattering using advantag es of the running-mass definition for the heavy quarks. The ABM11 PDFs obtained from the updated fit are in a good agreement with the recent LHC data on the W- and Z-production within the experimental and PDF uncertainties. We also perform a determination of…

The ABM parton distributions tuned to LHC data

We present a global fit of parton distributions at next-to-ne xt-to-leading order (NNLO) in QCD. The fit is based on the world data for deep-inelastic scatteri ng, fixed-target data for the Drell-Yan
