Decaying into the Hidden Sector

Understand

The existence of light hidden sectors is an exciting possibility that may be tested in the near future.

• If DM is allowed to decay into such a hidden sector through GUT suppressed operators, it can accommodate the recent cosmic ray observations without over-producing antiprotons or interfering with the attractive features of the thermal WIMP.
• Models of this kind are simple to construct, generic and evade all astrophysical bounds.
• We provide tools for constructing such models and present several distinct examples.
