Framework of Oviedo
◊ Using HEPPY Trees (same ones as used for SUSY SameSign and Multilepton)
● For producing yields/plots, etc we use git:IFCA-Uniovi/WZ
(a clone of the MPAF framework that we use for SUSY)
● Differences in lepton ID/ Isolatio wrt selection applied in
diboson group
●

◊
MuID → Medium ID (SUSY); Tight ID (SM)
ElID →MVA ID tight (SUSY); Cut based medium ID (SM)
Isolation: MiniIso (SUSY); relIso (mu), no explicit iso (e) (SM)
Working on implementing SM selection in Heppy trees (see last slide)
First results with this framework before summer using
Phys 14 samples

Updating our results using 25 ns Spring15 samples and 20
pb of data
Requiring only 3 leptons (our looser selection step)
◊ Full set of validation plots here for different selection steps

Still large differences. Work in progress
● Jon kindly agreed on producing yields for just one file
of this sample to speed up our turn around time
