Powheg: few changes in parameters
requested to merge atlas-physics/pmg/mcexperts/powheg-experts/athena:master-PowhegControl-FixSomeParameters into master
This makes two changes:
- remove the freezing of the
smartsig
parameter (for all processes) which made it impossible to be changed by users - this is needed for the Drell-Yan LQ processes - set
pdfreweight
to 0 by default inW_EW
andZ_EW
- this will remove the old-style pdf reweighting infos by default for these two processes, which was causing problems
