Description
We introduce the dark matter (DM) evolution process in the Sun
under a two-component DM scenario. In this picture, both DM species could be
captured by the Sun through DM-nucleus scattering and DM self-scatterings,
e.g. $\chi\chi$
and $\xi\xi$ collisions. In addition, the heterogeneous self-scattering due
to $\chi\xi$ collision is
essentially possible in any 2DM models. This new introduced scattering naturally
weaves the evolution processes of the two DM species that was assumed to evolve
independently. Moreover, the heterogeneous self-scattering enhances the number of
DM being captured in the Sun mutually. This effect significantly exists in a broad
range of DM mass spectrum. If the annihilation final state contains neutrinos,
the terrestrial neutrino detectors could distinguish whether DM is multicomponent or not.
