Circularly polarized gamma rays in effective dark matter theory
We study the loop-induced circularly polarized gamma rays from dark matter annihilation using the effective dark matter theory approach. Both neutral scalar and fermionic dark matter annihilating into monochromatic diphoton and Z-photon final states are considered. To generate the circular polarizat...
