resent an attempt to identify the SM Higgs boson at LHC in the channel (pp-bar {yields} HX {yields} W+ W-X {yields} l+ vl- v X). We use a multivariate processing of data as a tool for a better discrimination between signal and background (via Principal Components Analysis, Genetic Algorithms and Neural Network). Events were produced at LHC energies (MH = 140 - 200 GeV), using the Lund Monte Carlo generator PYTHIA 6.1. Higgs boson events (pp-bar {yields} HX {yields} W+W-X {yields} l+ vl- v X) and the most relevant background are considered.
