Theoretical Uncertainties in Electroweak Boson Production Cross Sections at 7, 10, and 14 TeV at the LHC

Understand

We present an updated study of the systematic errors in the measurements of the electroweak boson cross-sections at the LHC for various experimental cuts for a center of mass energy of 7, 10 and 14 TeV.

• The size of both electroweak and NNLO QCD contributions are estimated, together with the systematic error from the parton distributions.
• The effects of new versions of the MSTW, CTEQ, and NNPDF PDFs are considered.
