The potential to discover a standard model-like Higgs boson at the LHC in the mass range from 150–180 GeV, decaying into a pair of W bosons with subsequent leptonic decays, has been established during the last 10 years. Assuming that such a signal will eventually be observed, the analysis described in this paper investigates how accurate the signal cross section can be measured and how the observable lepton spectra can be used to constrain the mass of the Higgs boson. Combining the signal cross section with the analysis of the lepton spectra and assuming the SM Higgs cross section is known with an accuracy of , our study indicates that an integrated luminosity of about allows to measure the mass of a SM Higgs boson with an accuracy between 2 and 2.5 GeV.
