     4*  [http://feynrules.irmp.ucl.ac.be/raw-attachment/wiki/DMsimp/DMsimp_UFO.2.zip DMsimp_UFO.zip]: the s-channel model files in UFO format
     5* TO BE DONE: include  the s-channel+EW model files in UFO format

     7== NLO process samples for s-channel mediators==

     165*2015.06.11 - v0.1_alpha: alpha version. [[BR]]
     166*2015.06.16 - v0.2_alpha: alpha version : deleted “DMT” coupling (for spin-2 mediator model) from couplings_order.py. Added onlytops restriction to only allow vector and scalar mediators coupling to tops. (Thanks to Uli Haisch for testing).
