Compact Dark Matter Objects via $N$ Dark Sectors

Understand

We propose a novel class of compact dark matter objects in theories where the dark matter consists of multiple sectors.

• We call these objects $N$-MACHOs.
• In such theories neither the existence of dark matter species nor their extremely weak coupling to the observable sector represent additional hypotheses but instead are imposed by the solution to the Hierarchy Problem and unitarity.
• The crucial point is that particles from the same sector have non-trivial interactions but interact only gravitationally otherwise.
