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!

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

Category	old NP name	new NP name	def	Meaning
QCD scale uncertainties for other production modes	QCDscale_XX, QCDscale_XX1in, QCDscale_XX2in	QCDscale_XX, QCDscale_XX1in, QCDscale_XX2in, QCDscale_XX3in	XX=WH,ZH,qqH,ttH	signal scale uncertainty
Theory signal uncertainties (names not changed, as they have to be in agreement with CMS)		pdf_Higgs_XX	XX=ggH, qqH, VH, ttH or XX=1, 2, 3, 4 if a correlated signal pdf model is used	signal pdf uncertainty (can be correlated to pdf_XX if needed/wanted)
	ATLAS_BR_XX	ATLAS_BR_XX: to be used by individual analysis. Uncertainty values to be taken from here	XX=WW,ZZ,gg,tautau,bb,Zg	signal BR uncertainty for individual channels
		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. The ATLAS_PW_XX from the individual analysis will then be set constant in the combination to avoid double counting	XX=WW,ZZ,gg,tautau,bb,Zg	correlated signal BR uncertainty for the combination
	use QCDscale_(XX_)ANA_ or pdf_Higgs_(XX_)ANA_ for any analysis specific uncertainties that are clearly related to signal scale or PDF changes but can't use the NPs above
Theory background uncertainties (names not changed, as they have to be in agreement with CMS)	QCDscale_XX, QCDscale_XX1in, QCDscale_XX2in	QCDscale_XX, QCDscale_XX1in, QCDscale_XX2in, QCDscale_XX3in	XX=ttbar, VV, ggVV, ...	background scale uncertainty (VV is WW, WZ, and ZZ up to NLO, ggVV is gg->WW and gg->ZZ)
	pdf_XX		XX=gg,qg,qq	background pdf uncertainty (can be correlated to pdf_Higgs_XX if needed/wanted)
	use QCDscale_(XX_)ANA_ or pdf_(XX_)ANA_ for any analysis specific uncertainties that are clearly related to some background scale or PDF changes but can't use the NPs above
