Description

In a two-component dark matter (DM) set-up, when DM$_1$ is in equilibrium with the thermal bath, the other one, DM$_2$, can be equilibrated only by the sizeable interaction with the DM$_1$, even without any connection with the visible-sector particles. We affirm that such DM candidates (DM$_2$) have unique `freeze-out' characteristics impacting the relic density, direct, indirect and collider search implications, and propose to classify them as $\rm pseudo-{\tt FIMP} ~(p{\tt FIMP})$. Here, We have accentuated the dynamics of $\rm p{\tt FIMP}$ in a model-independent manner by solving the generic coupled Boltzmann Equations (cBEQ), as well as with a concrete model illustration. Also, we have illustrated its detectability for different kinds of model possibilities.
