Simplified Models for Coannihilating Dark Matter

This is a set of simplified models which include a dark matter candidate, a coannihilation partner and a mediator in various representations of SU(3)xSU(2)xU(1) based on The Coannihilation Codex.

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 s-channel mediator: $\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (3,2,\tfrac{7}{3})_\mathrm{F} \qquad \mathrm{M} \equiv (3,2,\tfrac{7}{3})_\mathrm{S}$
  • Triplet diquark s-channel mediator: $\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (3,1,-\tfrac{2}{3})_\mathrm{F} \qquad \mathrm{M} \equiv (3,1,-\tfrac{2}{3})_\mathrm{S}$
  • Sextet diquark s-channel mediator: $\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (6,1,\tfrac{8}{3})_\mathrm{F} \qquad \mathrm{M} \equiv (6,1,\tfrac{8}{3})_\mathrm{S}$
  • Scalar octet s-channel mediator: $\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (8,2,1)_\mathrm{F} \qquad \mathrm{M} \equiv (8,2,1)_\mathrm{S}$

A more detailed description for each of the models including validation for MadGraph? and Micromegas/MadDM is available in the manual attached.
