ConclusionsConclusions
Event generation with cut on boson pt seems to be Event generation with cut on boson pt seems to be workingworking
WlnuNp1 – WlnuNp4 are fine Still need to understand the reason of failures in some jobs for
Np0 and Np5inclusive
I guess next step – to produce more “official” I guess next step – to produce more “official” datasetsdatasets
How to proceed ? Private production or request to production team ?
Which release should be used ? Output from 17.7.0 might be incompatible with 17.2.X.Y
How many events are needed ?
