Description
As experimental data is becoming more precise, understanding the impact of the uncertainties in the errors, especially the systematic errors, is increasingly becoming a significant focus of PDF groups. In this talk we will explain how the error on errors can be modelled and how this framework can be applied to both uncorrelated and correlated systematic errors, and discuss the potential relationship to the PDF tolerance. We then investigate the PDF fits for ATLAS W,Z Data and the ATLAS 7 TeV Jet data with relation to this technique.
