| 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.

| - | There is a Rivet analysis provided to all interested parties. **Please note, the routine is not finalised until marked as such.** A few observables that were discussed still have to be added. Nonetheless, it can already be used to test your setup and/or produce preliminary results. | + | There is a Rivet analysis provided to all interested parties. **The routine is now finalised and can be used for production.** |
