Effective Operator Models for Semi-Annihilating Dark Matter

Presented by Dr. Andrew SPRAY

Content

Semi-annihilation is a generic feature of dark matter which is stabilized by a symmetry group larger than Z2. We systematically classify and enumerate effective operators up to dimension 6 for scalar and/or fermionic dark matter, with a focus on models where annihilation is suppressed. We show when and how different two-to-two processes are generated from a single effective operator. We additionally use searches for high energy gamma rays, positrons and neutrinos to set limits on the Wilson coefficients of these operators for models with a unique dark matter candidate. Finally we briefly discuss complete models inspired by this framework.
