Query: Top Quark Production at the LHC   Measurements of the production cross section for top quark pairs and the
single top quark by the ATLAS and CMS collaborations at the LHC are presented.
Improved measurements at sqrt(s)=7 TeV as well as new measurements at sqrt(s)=8
TeV are highlighted. All the measurements are in good agreement with the
