  1. Search for doubly charged Higgs bosons in three lepton channelsat √s=7TeV at CMS(Fall11 MC data analysis) 01. 08. 2012. Sungeun Lee Sungkyunkwan University

  2. Introduction • Existence of non-zero neutrino masses • Type II seesaw mechanism • Higgs triplet model • Pair-production process & Associated production process • limits on the F++ mass • Limit between 112 and 355 GeV

  3. Analysis When one lepton is missing in pair production channel • Luminosity : 4.638 fb-1 • Lepton selection - muon : pt>10, | |<2.4, Global Muon, nchi2<10, d0<0.02, sip<4, Good muon, valid hit>20, nstation>0 - electron : pt>10, | |<2.5, nchi2<10, d0<0.02, sip<4, eidMedium • Event selection - - (between the same sign di-leptons) • Fall11 data
