Phenomenology of a two-component dark matter model

We study a two-component dark matter model consisting of Dirac fermion and complex scalar charged under new U(1) gauge group in the hidden sector. The plays dominant component which explains measured DM relic density Universe. It has no direct coupling to ordinary standard particles, thus evading strong constraints from detection experiments. is self-interacting through light boson it would be possible address that this can resolution small scale structure problem boson, interacts with sector, also stable composes subdominant component. investigate parameter space allowed by current experimental phenomenological bounds. discuss sensitivity future experiments such as SHiP, DUNE ILC, for obtained space.
