SM Higgs Searches for $H\rightarrow WW^{(*)}\rightarrow l^+\nu l^-\nu$ with a Mass between 150-190~GeV at LHC

For the Standard Model Higgs boson in the mass range around 170~GeV thesignificance in the $H\rightarrow ZZ^* \rightarrow 4l$ channel is relativelysmall, due to the suppression of the $ZZ^*$ branching ratio as the $WW$ decay mode opens up. In this mass range the leptonic branching ratioof the $WW^*$...

description For the Standard Model Higgs boson in the mass range around 170~GeV thesignificance in the $H\rightarrow ZZ^* \rightarrow 4l$ channel is relativelysmall, due to the suppression of the $ZZ^*$ branching ratio as the $WW$ decay mode opens up. In this mass range the leptonic branching ratioof the $WW^*$ mode is approximately 100 times larger than the $ZZ^*\rightarrow 4l$ mode. For such leptonic W decays, it is however not possible to reconstruct a mass peak. Instead the transverse mass distributionmust be used to identify the presence of a Higgs signal and to extract information on its mass.
