  Vector Boson Fusion (VBF) is a promising discovery level process in the Higgs
search at the LHC. Nevertheless, that search depends on understanding the
detector response to a good level of accuracy. Therefore, it is useful to have
a known process by which to validate the search methodology. The VBF production
of a Z with subsequent leptonic decay appears to be ideal in that the Feynman
diagrams are the same for Z and Higgs VBF production and there is a clean
resonance in the dilepton spectrum.
