| After discussions with both ATLAS, CMS, aMC@NLO and POWHEG people, it has been found out that it is valuable to include in the LHE format some extra information about event reweighting. And thus comes the problematics of standardizing the way to pass this information. This would allow to have, in one single LHE file, unweighted events corresponding to a given MC setup (for instance, central scales, central PDF, etc…), together with weights related to the variation of one or several of the MC parameters. | After discussions with both ATLAS, CMS, aMC@NLO and POWHEG people, it has been found out that it is valuable to include in the LHE format some extra information about event reweighting.
