Nuisance parameter renaming schema

Motivation for renaming:

  • So far we present our result with one uncertainty, that results from the combination of many sources
  • For publication we want to be able to separate and name the dominant theory and experimental uncertainty components
  • For internal validation we want to be able to understand in detail, how different sources/groups of uncertainties influence our results
  • Almost all of this is possible today, but it is very hard to identify which NPs belong into same categories. A consistent naming scheme should help here a lot!

ggH specific QCD scale QCDscale_ggH QCDscale_ggH   signal scale uncertainty
-QCDscale_ggH_e0, QCDscale_ggH1in QCDscale_ggH_ptH_m01 A shift towards harder radiation (more jets) has a positive uncertainty amplitude (i.e. a positive pull of the associated NP would mean that data favours harder radiation) signal scale uncertainty associated with both 0->1 jet migration in JVE method, and pT Higgs defined categories.
QCDscale_ggH_e1 QCDscale_ggH_e1   veto effiency for 1<->2 migration, used by JVE method to define the 1 jet exclusive category in the H->WW analysis
QCDscale_ggH2in QCDscale_ggH_m12   signal scale uncertainty associated with VBF and VH selection
QCDscale_ggH3in QCDscale_ggH_m23   signal scale uncertainty associated with 3rd jet veto

The following table shows which QCDscale ggH NPs affect which analysis, and in which category for the final Run 1 papers:

QCDscale_ggH low-pTt ggF 0,1,2in -
QCDscale_pTH_m01 low/high pTt ggF 0,1,2in (via e0) boost
QCDscale_e1 - - 1,2in -
QCDscale_m12 VBF, VH VBF VBF VBF, boost
QCDscale_m23 VBF - (no 3jveto) VBF VBF

ATLAS_PW_XX : to be used by the combination for the correlated BR model. NPs will be added in the combinations, individual analysis don't have to include them.
