EWK Jets + EW bosons: LHC tunes  20 June

	•	Participants: 18 on vidyo, 4 in room
	•	tunes
	•	herwig (Johannes)
	•	hadronization from lep
	•	intrinsic kt from DY 
	•	MPI from UE Tevatron/LHC
	•	discussion
	•	should one use LHC to cover color connection ?
	•	what about delta chi2
	•	Sherpa
	•	hadr with lep
	•	LHC DY for intrinsic DY
	•	MPI and bean remnant to LHC
	•	mainly using ATLAS data, extend to CMS also
	•	discussion
	•	born lepton, should not be used
	•	DY first bins, how to disentangle shower ?
	•	stopping scale of shower ?
	•	Autotunes(Johannes)
	•	what goes into tune ?
	•	human factor
	•	many measurements of same quantity, correlations ?
	•	approach to take correlations into account
	•	automatically select weights
	•	Discussion
	•	no replacement for professor
	•	CMS P8 tunes (Efe)
	•	NNLO tunes work for min bias and UE
	•	CP0-5 tunes
	•	some tuns need rapidity ordering and as=118
	•	Discussion
	•	use NNPDF_MC sets which are positive 
	•	Discussion
	•	reproducibility
	•	procedure how it is used 
	•	safe it on gitlab, easy procedure
	•	agree on parameters which should not be changed....
	•	std set of observables and std set of weights which is the basis, other observables can be added....
	•	check that chi2 of basic observables is not changes
	•	start with Monash tune data sets, and improve
	•	aim: start now, try for autumn
	•	also discuss with PDF people etc
