== Description of the model ==

This is simplified dark matter models for NLO. 
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.)
* ...

and different types of mediators:

* s-channel
  * Y0 (spin-0)
  * Y1 (spin-1)
  * Y2 (spin-2) (to be done.)
  * ...

* t-channel (to be done.)

One can find the model lagrangian in the [http://feynrules.irmp.ucl.ac.be/raw-attachment/wiki/DMsimp/note.pdf note].

=== Model files ===
*  TBD : the s-channel model files in UFO format
* TO BE DONE: include  the s-channel+EW model files in UFO format

=== NLO QCD process samples for s-channel mediators===
Remember that "scalar" below means scalar/pseudoscalar and "vector" means vector/axial-vector.
