Boson boson scattering and Higgs production in boson boson fusion will be actively investigated at the CERN LHC. We have performed a parton level study of all processes of the type q(1)q(2) -> q(3)q(4)q(5)q(6)l(+) l(-) using for the first time a full fledged six fermion Monte Carlo event generator which employs exact matrix elements at O(alpha(6)(em)). We have examined Higgs production in vector boson fusion followed by the decay chain H -> ZZ -> l(+) l(-) jj, including exactly all electroweak irreducible backgrounds. In the high mass region we have compared the case of a relatively light Higgs with the no-Higgs results. The integrated cross section for the latter case is more than twice that in the former for a minimum invariant mass of the ZV pair of about 800 GeV. We find, in a preliminary analysis at parton level, that, summing up the muon and the electron channels, about 25 events are expected in the light Higgs case for L = 100 fb(-1).
