W,Z production at ATLAS and determination of the strange sea density
The talk presents the two most recent Atlas publications on precision measurements of W and Z fiducial cross sections based on 2010 data and their QCD analysis. The NNLO QCD fit is jointly performed with HERA I DIS data, suggesting a symmetric light sea at x about 0.01.
