Description
There are strong cosmological and astrophysical constraints for thermal dark matter below the GeV scale: CMB excludes s-channel annihilation cross-sections for thermal dark matter below 10 GeV. What kind of special properties dark matter should have to evade such strong constraints ?
Resonant annihilation is one possibility.
First, I will explain the effects of resonances on the formation of the dark matter relic with a model-independent approach.
Then, I will focus on light dark matter interacting with quarks and gluons, introducing the Chiral Lagrangian, and discussing if resonant s-wave models can evade the constraints that are obtained from CMB and indirect detection.
