Search for `invisible' Higgs signals at LHC via Associated Production with Gauge Bosons
The paper says
“By exploiting this second signature, we show that invisible branching ratios of Higgs bosons, BRinv, larger than ∼ 0.42(0.70) can be probed at 5σ level for MH = 120(160) GeV respectively, assuming an accumulated luminosity of L=100 fb−1.”

The paper
Abstract
A light Higgs boson with substantial branching ratio into invisible channels can occur in a variety of models with: light neutralinos, spontaneously broken lepton number, radiatively generated neutrino masses, additional singlet scalar(s) and/or right handed neutrinos in the extra dimensions of TeV scale gravity. We study the observability of the WH and ZH modes at LHC with H decaying invisibly, by carrying out a detailed simulation with two event generators HERWIG and PYTHIA and realistic detector simulations (GETJET and CMSJET). We find that the signal with `single lepton plus missing ET' resulting from WH production suffers from a very large background due to the (off-shell) W* production via the Drell-Yan process. In contrast, the ZH mode provides a clean signal in the `dilepton plus missing ET' channel. By exploiting this second signature, we show that invisible branching ratios of Higgs bosons, BRinv, larger than ∼ 0.42(0.70) can be probed at 5σ level for MH = 120(160) GeV respectively, assuming an accumulated luminosity of L=100 fb−1.

At the LHC, experiments have explored Higgs portal scenarios in which the 125 Higgs boson has substantial coupling with WIMP candidates (such as singlet scalar S, vector V, fermion $χ$) to induce interaction between WIMP and nucleon; the WIMP could be invisible decay products of the Higgs boson [ref] .
