  • ttbar associated production with a spin-0 mediator coupling only to tops at NLO
import model DMsimp_UFO-onlytops

Loop-induced samples at LO

  • loop-induced mono-jet with a spin-0 mediator at LO
import model DMsimp_UFO-onlytops  
generate p p > xd xd~ j DMV=0 [QCD]
  • loop-induced monojet with a spin-1 mediator at LO
import model DMsimp_UFO-onlytops
generate p p > xd xd~ j DMS=0 [QCD]
  • loop-induced mono-Higgs with a spin-0 mediator (no interaction between the h and the mediator) at LO
import model DMsimp_UFO-onlytops
generate p p > xd xd~ h DMS=2 DMV=0 [QCD]
  • loop-induced mono-Higgs with a spin-1 mediator (no interaction between the h and the mediator) at LO
import model DMsimp_UFO-onlytops
generate p p > xd xd~ h DMV=2 DMS=0 [QCD]
  • loop-induced mono-Z with a spin-0 mediator (no interaction between the Z and the mediator) at LO
import model DMsimp_UFO-onlytops
generate p p > xd xd~ z DMS=2 DMV=0 [QCD]
  • loop-induced mono-Z with a spin-1 mediator (no interaction between the Z and the mediator) at LO
import model DMsimp_UFO-onlytops
generate p p > xd xd~ z DMV=2 DMS=0 [QCD]
  • loop-induced mono-photon with a spin-0 mediator (no interaction between the photon and the mediator) at LO
import model DMsimp_UFO-onlytops
generate p p > xd xd~ a DMS=2 DMV=0 [QCD]

NOTE: this process gives zero because of C parity for both scalar and pseudoscalar mediators. It is here for reference.

  • loop-induced mono-photon with a spin-1 mediator (no interaction between the photon and the mediator) at LO

Version updates

*2015.06.11 - v0.1_alpha: alpha version.
*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).
