Physics Study of the Higgs Decay Channel H -> WW -> 2mu 2nu

We report the physics study of the Higgs decay channel H -> WW -> 2mu 2nu, performed using Monte Carlo generated data processed by the CMS full simulation and reconstruction programs. The optimization of the selection criteria and the study of the different background contributions are reported, describing in detail the methods developed to evaluate the related systematical uncertainties. The cross sections of the relevant physics processes, estimated at the leading order (LO) in the full simulation, are corrected at the next-to-leading order (NLO), and the resulting expected signal significance is given as a function of the Higgs mass.
