 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.

 Scales: ​  ​muR/​muF depending on calculation,​ of course. However, usually there is freedom on pp->h+0j level, thus please choose a scale that reproduces mH/2 in the 0j limit, eg. HT'/2 instead of HT' in pp->h+3j at fixed order. All other scales as needed. Scales: ​  ​muR/​muF depending on calculation,​ of course.
