The aim is to study various non-trivial observables of experimental interest/relevance with calculations implementing various different perturbative QCD approximations. There is a [[http://rivet.hepforge.org/|Rivet]] routine provided and all participating parties are encouraged in using it. | The aim is to study various non-trivial observables of experimental interest/relevance with calculations implementing various different perturbative QCD approximations.
