Description
A scalar dark matter model interacting with the standard model sector via top-quark portal as well as Higgs portal is presented. In the model a scalar dark matter $S$ and a vector-like fermion $T$ are new physics particles and assumed to have odd parity under a $Z_2$ symmetry, while all the standard model fields have even parity. The impacts of new top-quark portal interaction, $y_{ST} S \bar{T} t_R +h.c$, on dark matter phenomenology and collider searches will be emphasized.
