Comments from Mario • Well the first obvious thing I see is that your luminosity is 4.6 /fb which sounds like you are using the old lumiCalc2.py that doesn't have the correct 2011 lumi normalization. The lumi should be around 4.91 /fb. • Secondly you seem to use a different electron ID. We used CiC Tight with additional criteria (conversion rejection, charge triple check etc), you use eidLoose (which I think is some old working point that is by default in PAT). • Can you define the sqrt(sum(pt*pt)) for me? Do you sum over all possible lepton combinations or you take the quadratic sum of all lepton pt's (so while we added the pt's linearly you add quadratically)?

AN • Title Search for a doubly charged Higgs boson in the decay channel to 3 or 4 final state leptons using the CMS data at 7TeV • Abstract A search for a doubly charged Higgs boson in the decay channel to 3 or 4 final state leptons is presented using the pp collisions data from the LHC at 7TeV. The data analysed correspond to an integrated luminosity 4.983 fb-1 collected by CMS detector at LHC. The inclusive search is performed in events with the final state leptons which are consist of electrons and muons from the decay of the pair production and the associated production.
