Cosmic Rays from Higgs Portal Dark Matter

Dark Matter indirect search is to find the signals of Dark Matter annihilation or decay from cosmic rays. In this talk, I will shortly review the current status of cosmic ray search on Dark Matter, and focus on the antiproton constraints and forecast its future sensitivities. As a compiling model, the scalar Higgs portal is able to provide a connection between the visible world and the dark sector via a renormalizable coupling with the Higgs boson. I will apply this model to illustrate the importance of antiproton constraints by comparing to other observations.
