Revision as of 13:23, 12 June 2009

Identifying/analyzing observables, ratios of observables, systematic uncertainties (renorm.scale, PDFs), obtaining cross sections from public codes/ntuples. The observables might involve both jets and leptons. Identify for which process/observable NLO calculations are available. What is suitable for start-up (eg. normalization issues, Drell-Yan, top, ...)
