Introduction
• In models with expanded Higgs sector, one can have Higgs triplets.
Doubly charged Higgs
• Pair production : through Drell-Yan process
• Decays : • In this analysis, we only consider e-μ decays (Br(H++ l+l+)=1 is assumed, l+l+ = e+e+ or e+μ+ or μ+μ+)

Samples• Used CMSSW version : 4_4_2
• MC signal samples (√s=7TeV) : full simulation data → H++H-- to l+l+l-l-
→ M(H±±) = 150, 170, 200, 250, 300, 400, 500GeV • MC background samples : full simulation data → ZZJetsTo4L, WZJetsTo3LNu TTTo2L2Nu2B, DYJetsToLL
• Data samples : 2011 data, Lint = 4.983 fb-1

• Electron selection pT>10 GeV, |η|<2.5, |d0|<0.02, eidLoose
• Muon selectionpT>10 GeV, |η|<2.4, global muon, good muon, hits_val>20, nstation>=1
• Preselection : nlep+>=2, nlep->=2, relIso<0.5, Mll>10 GeV
- relative isolation : (IsoPttrack + IsoPtecal + IsoPthcal)/pt < 0.5
• Event selection - mass dependent cut- quad-lepton mass : M4l > cut value
