**DMsimp - Alpha version**

## Model files

- DMsimp_UFO.zip: the s-channel model files in UFO format
- TO BE DONE: include the s-channel+EW model files in UFO format

## 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).
