Description
In this talk I will discuss the indirect detection signals for a self-consistent hidden U(1) sector, containing a fermionic dark matter candidate, dark Z' gauge boson and a dark Higgs. The presence of the scalar, the dark Higgs, provides a mass generation mechanism for the dark sector particles, and for some couplings is required in order to avoid unitarity violation at high energies. I will show that the inclusion of this scalar to the sector opens up a new s-wave annihilation channel for indirect detection searches, providing rich phenomenology.
