The signal yield is for the corresponding mass point and is normalised to the luminosity of 36.1fb-1. The dominant background from prompt-lepton sources is from the WZ process in the 2ss channel. For the 3 and 4 channels, the dominant background from prompt-lepton sources is from WZ and tt¯V processes. The overall signal acceptance A and the upper limit of extra contribution to each signal region at 95% confidence level n95 are also presented. The data and SM prediction yields obtained for mH±±=500 GeV are also valid for mH±±=600 and 700 GeV
