NLO process samples for s-channel mediators

Remember that "scalar" below means scalar/pseudoscalar and "vector" means vector/axial-vector.

  • NLO vector mediator + jets
import model DMsimp_UFO 
generate p p > xd xd~ j DMV=2 DMS=0 QCD=1 QED=0 [QCD]
generate p p > xd xd~ j j  DMV=2 DMS=0 QCD=2 QED=0 [QCD]
  • NLO scalar mediator + jets (the scalar coupling to light quarks with Yukawa's proportional to the SM ones (MFV))
import model DMsimp_UFO-full
generate p p > xd xd~ j DMV=0 DMS=2 QCD=1 QED=0 [QCD]
generate p p > xd xd~ j j  DMV=0 DMS=2 QCD=2 QED=0 [QCD]
  • NLO ttbar associated production (for vector coupling to both top and light quarks) at NLO
import model DMsimp_UFO 
generate p p > xd xd~ t t~ / y0 [QCD] 
  • NLO ttbar associated production with a vector mediator coupling only to tops
import model DMsimp_UFO-onlytops
define p = p b b~
define j = p
generate p p > xd xd~ t t~ / y0 [QCD] 
  • NLO ttbar associated production with a scalar mediator coupling only to tops
import model DMsimp_UFO-onlytops
define p = p b b~
define j = p
generate p p > xd xd~ t t~ / y1 [QCD] 
  • NLO associated production with a Z with a vector mediator Y1 coupling to light quarks (no coupling of a Z with Y1)
import model DMsimp_UFO
generate p p > xd xd~ z / y0 [QCD]

  • NLO associated production with a W with a vector mediator Y1 coupling to light quarks (no coupling of a W with Y1)
import model DMsimp_UFO
define wpm = w+ w-
generate p p > xd xd~ wpm / y0 [QCD]
  • NLO associated production with a gamma with a vector mediator Y1 coupling to light quarks (no coupling of a gamma with Y1)
import model DMsimp_UFO
generate p p > xd xd~ a / y0 [QCD]

LO processes loop (top-quark) induced

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

  • LO mono-photon loop-induced with vector mediator (no interaction between the gamma and the vector mediator)
import model DMsimp_UFO-onlytops
generate p p > xd xd~ a DMV=2 DMS=0 [QCD]

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).
