Description

Most indirect dark matter searches consider only signals from decay or two-body annihilation. I will discuss the general scenario where more than two dark matter particles participate in the annihilation process. Such processes can be greatly enhanced at low velocities, and generically have different redshift dependence than standard decay/annihilation signals. I will describe and examine the cosmological and astrophysical constraints on such multi-body annihilation processes.
