The following are the selection cuts defined as "W_Selection_1"

Trigger Cuts Single EM trigger {EM_HI , CEM20 , CEM15}Kinematic Selection Cuts emf>0.9 , iso<0.2 , |id|<=12 , MET_METNE>25.0 GeVEvent is kept if it passes: Trigger and kinematic selection cuts and has at least one EM object with |etaD|<0.8 and pT>20 GeV

The following are the selection cuts defined as "W_Selection_2"

Trigger Cuts Single EM trigger {EM_HI_EMFR8 , EM_HI , EM_HI_SH , EM_HI_SH_TR , EM_HI_TR , EM_HI_L2 , EM_MX}Kinematic Selection Cuts emf>0.9 , iso<0.2 , |id|<=12 , MET_METNE>25.0 GeVEvent is kept if it passes: Trigger and kinematic selection cuts and has at least one EM object with |etaD|<0.8 (or |etaD|<2.4 if available) and pT>20 GeV

The following are the selection cuts defined as "W_Selection_3"

Trigger Cuts Single EM trigger {EM_HI_EMFR8 , EM_HI , EM_HI_SH , EM_HI_SH_TR , EM_HI_TR , EM_HI_L2 , EM_MX , EM_MX_EMFR8 , EM_MX_SH , EM_MX_TR}Kinematic Selection Cuts emf>0.9 , iso<0.2 , |id|<=12 , MET_METNE>25.0 GeVEvent is kept if it passes: Trigger and kinematic selection cuts and has at least one EM object with |etaD|<2.4 and pT>20 GeV

Conclusions sur le streaming…

Partir du skeaming du Higgs:• couper plus en HM8 (<50 ?),• rajouter un cut sur l’isolation (iso<0.15 ?) • un cut sur le missing ET (>20 ou 25 GeV)• Puis regarder le nombre de jets???
