Abstract: In this talk, We present constraints on inert triplet scalar dark matter which arise from observables at the LHC.
We discuss possible decay of Higgs boson to dark matter candidate and apply current experimental data for invisible Higgs decay and $R_{\gamma\gamma}$ to constrain parameter space of our model. We also investigate constraints on dark matter coming from forthcoming measurement, $R_{Z\gamma}$ and mono-Higgs production. We then use FermiLAT data to put constraints on parameter space of Inert Triplet Model.
