= Simplified Models for Coannihilating Dark Matter =
This is a set of simplified models for coannihaliting dark matter based on [http://arxiv.org/abs/1510.03434 The Coannihilation Codex]. Each of the models includes a dark matter candidate, a coannihilation partner and a mediator in various representations of {{{SU(3)xSU(2)xU(1)}}}. These models with minimal particle content provide a way to design generic collider searches for coannihilation, whose results can then be applied to more specific models.


--------------------------------
== Authors ==
The implementation of the models has been done by
* Anna Kaminska (JGU Mainz)
* Maikel de Vries (JGU Mainz)
in collaboration with Michael Baker, Joachim Brod, Malte Buschmann, Sonia El Hedri, Joachim Kopp, Jia Liu, Andrea Thamm, Xiao-Ping Wang, Felix Yu and José Zurita.

--------------------------------
== Model Description ==
Each of the models introduces three new fields: DM (dark matter candidate), X (coannihilation partner), M (s- or t-channel mediator).
Currently the set of models comprises:
* Leptoquark model:
{{{
#!latex
$\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (3,2,\tfrac{7}{3})_\mathrm{F} \qquad \mathrm{M}_s \equiv (3,2,\tfrac{7}{3})_\mathrm{S}$ 
}}}
* Triplet diquark model:
{{{
#!latex
$\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (3,1,-\tfrac{2}{3})_\mathrm{F} \qquad \mathrm{M}_s \equiv (3,1,-\tfrac{2}{3})_\mathrm{S}$ 
}}}
* Sextet diquark model:
{{{
#!latex
$\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (6,1,\tfrac{8}{3})_\mathrm{F} \qquad \mathrm{M}_s \equiv (6,1,\tfrac{8}{3})_\mathrm{S}$ 
}}}
* Scalar octet model:
{{{
#!latex
$\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (8,2,1)_\mathrm{F} \qquad \mathrm{M}_s \equiv (8,2,1)_\mathrm{S}$ 
}}}


A more detailed description for each of the models including validation for !MadGraph and Micromegas/MadDM is available in the [http://feynrules.irmp.ucl.ac.be/attachment/wiki/SimplifiedDM/res_met_manual.pdf manual (pdf)].
