ggF | Uncertainties in kinematic regions | Recommendation (LHCXSWG-INT-2017-001); Tool Working on a public note with the new recommendation with WG2 |
--- Summer 2021 |
It is a set of per-event weights, one for each source of uncertainty, to plug&play using the simplified/template cross section setup. Implemented everything in MINLO NNLOPS, being this the reference and the most up to date generator. Re-weighting Powheg to NNLOPS is mandatory , since the uncertainties have been calculated with a given perturbative order, and if it is not matched with the generator, the result may be inconsistent. Recent progress: High-Pt results from WG1 (see next line) incorporated+ agreement reached on NP definition between ATLAS, CMS and theory community. |
