New physics coupled to the Higgs boson may hide it in the standard decaychannels to be investigated at LHC. We consider the models where new invisibledominant decay modes of the Higgs boson are responsible for this hiding. Wepropose to study at LHC the weak boson production associated with heavy quarks:our analysis revealed that boson pair invariant mass distribution is sensitiveto both mass and width of the invisible Higgs boson, if it is not too far fromthe weak boson pair threshold. We present tree-level results for the mostrelevant cases of top quarks and of bottom quarks in Standard Model extensionswith large $b$-quark Yukawa coupling. We argue that QCD corrections do notspoil these results allowing for unambiguous extraction of the Higgs boson massand width from the analysis of large enough amount of data.
