The discovery of a 125 GeV Higgs and its coupling measurements do not
rule out beyond standard model physics scenarios most of which contain
a dark matter candidate. The Higgs boson can act as a candle to dark
matter searches by decaying into a pair of stable weakly interacting
particles. This invisible decay of the Higgs boson is motivated in a
variety of BSM physics models like SUSY, Extra dimensions, etc. This
talk will focus on the status of invisible branching ratio of the
Higgs at the LHC from considerations of global fit constraints on
coupling measurements along with direct searches. Finally I will
provide a comprehensive analysis of signals of invisible Higgs at the
LHC.
