Description of the model

This is simplified dark matter models for NLO.

The mixed spin-0 mediator model is a LO model for MadDM with the inclusion of effective ggY and aaY couplings.

Our lagrangian consists of different types of DM:

  • Xr (real scalar DM)
  • Xc (complex scalar DM)
  • Xd (Dirac spinor DM)
  • Xm (Majorana spinor DM) [to be done.]
  • Xv (vector DM)
  • ...

and different types of mediators:

  • s-channel
    • Y0 (spin-0)
    • Y1 (spin-1)
    • Y2 (spin-2)
    • ...
  • t-channel [to be done.]

(The model keeps all the quark masses finite, and apply only to tree-level processes.)
