Simplified Models for Coannihilating Dark Matter
This is a set of simplified models for coannihaliting dark matter based on 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. Another set of simplified models where the mediator is integrated out and X is colored have been presented in Simplified Phenomenology for Colored Dark Sectors and the UFO files can be generated using the FR-CDS package.
Authors
The implementation of the models has been done by
- Anna Kaminska (JGU Mainz, akaminsk@…)
- Maikel de Vries (JGU Mainz, mdevrie@…)
- Felix Yu (JGU Mainz, yu-001@…)
- José Zurita (KIT Karlsruhe, jose.zurita@…)
in collaboration with Michael Baker, Joachim Brod, Malte Buschmann, Sonia El Hedri, Joachim Kopp, Jia Liu, Andrea Thamm, Xiao-Ping Wang and Felix Yu.
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 (lq_met):
$\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (3,2,\tfrac{7}{3})_\mathrm{F} \qquad \mathrm{M}_s \equiv (3,2,\tfrac{7}{3})_\mathrm{S}$
- Triplet diquark model (dq3_met):
$\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (3,1,-\tfrac{2}{3})_\mathrm{F} \qquad \mathrm{M}_s \equiv (3,1,-\tfrac{2}{3})_\mathrm{S}$
- Sextet diquark model (dq6_met):
$\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (6,1,\tfrac{8}{3})_\mathrm{F} \qquad \mathrm{M}_s \equiv (6,1,\tfrac{8}{3})_\mathrm{S}$
- Scalar octet model (so_met):
$\mathrm{DM} \equiv (1,1,0)_\mathrm{M} \qquad \mathrm{X} \equiv (8,2,1)_\mathrm{F} \qquad \mathrm{M}_s \equiv (8,2,1)_\mathrm{S}$
A more detailed description for each of the models including validation for MadGraph and Micromegas/MadDM is available in the manual (pdf).
Interfaces
These models files work with and have been tested for several programs. The UFO output has been tested to work with MadGraph 5 and MadDM. As well as the CalcHEP model files which have been tested to work with MicrOMEGAs. See the manual for more details.
