  Results are presented for the search for invisible Higgs boson production
using the full LHC dataset corresponding to integrated luminosity of 5.1 fb^-1
and 19.6 fb^-1 of proton-proton collision data at sqrt(s)= 7 TeV and 8 TeV
(respectively) collected by the CMS detector. The invisible Higgs is searched
for in final states of missing transverse energy, with two leptons from a
recoiling Z boson. No significant excess is found beyond standard model
predictions, and limits are obtained on the branching fraction of the Higgs
boson to invisible particles.
