Boson fusion and Higgs production at the CERN LHC in six fermion final states with one charged lepton pair

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).
