PROCESS

Specify the process we are producing.

Always using number if more than one same particle, and Arrange in alphabetical order

• Using DYto2L instead of DYtoLL

• Usng WtoLNu and WtoQQ to distinguish decay of W boson

• Using TT instead of TTbar

• Using TtoLNu and TbartoLNu to distinguish top and anti-top

• Using WWto2L2Nu instead of WWtoLLNuNu (or WWto2Nu2L)

• Using WWtoLNu2Q instead of WWtoLNuQQ

Merging information if it is not confusing

• Using WZto3LNu instead of WZtoLNu2L

• Using WWto4Q instead of WWto2Q2Q

BINNING

When producing binning samples, e.g., DY process with maximum 4jet in LHE level,

• The inclusive process name: DYto2L-4Jets

• the corresponding jet-binned sample, e.g., 1 jet at LHE-level: DYto2L-4Jets_1J

N.B.: check the hyphen and underscore in this case carefully!!

Other binning cases are trivial, e.g., DYto2L-4Jets_MLL-60to90, DYto2L-4Jets_HT-100to200 ...

bin e.g. "600toInf" should be "600" directly, i.e., no need to add "Inf"

FILTER

Some complicated cases:

• DYto2L-4Jets_BEnriched: GEN filter requiring for b quarks from parton shower (maximum jet multiplicity is 4 in LHE level )

• DYBto2LB-4Jets: LHE requiring one b quark in ME (e.g. p p > e+ e- b) (maximum jet multiplicity is 4 in LHE level )

The generators to be used are:​

Pythia6	pythia6
Pythia8	pythia8
Herwig6	herwig6
Herwig++	herwigpp
Herwig7	herwig7
Sherpa	sherpa
MadGraph/MG5_aMC@NLO (LO)	madgraph
MadGraph/MG5_aMC@NLO (LO) e.g. showered with Pythia8	madgraph-pythia8
MadGraph/MG5_aMC@NLO (NLO)	amcatnlo
Alpgen	alpgen
MC@NLO	mcatnlo
POWHEG	powheg
HARDCOL	hardcol
BCVEGPY 2	bcvegpy2
...	...

If there are specialized decay tool used, please append this to the name, e.g. if EvtGen was used after Pythia8, use ...pythia8-evtgen, ...pythia8-tauola, ...pythia8-photos

When madspin is used, e.g., powheg-madspin-pythia8
