Description
The goal is to outline and start addressing the issues relevant for a uniform definition of cross sections across the experiments, and for the combination of experimental results, including W+gamma final states
Topics to be covered in the discussion:
* Common fiducial volumes. Uncertainty in extrapolation of one experiments' results to the others' volume
* optimal fiducial volume (minimize theoretical uncertainties)
* effects of crack interpolations
* possible agreement on theoretical setup (inclusion of QED/EW corrections, reference external PDF set, reference MC codes, etc)
* "standardize" correlated and uncorrelated systematic uncertainties to be addressed, and think towards a common approach.
* averaging procedures
