MadDM

Two dark matter components

Asked by Y Zhong

Hi,

I am working on a model of excited DM. In the model, I have two dark matter components: chi and psi, with a scalar mediator s0 connecting to the SM. I would like to compute the relic density of chi and psi.

Under the maddm 2.1 MG5 interface, I have tried

import model my_model
define darkmatter chi psi
generate relic_density
output my_output

It seems only chi is identified as DM. I was wondering if there is something I have missed? The output is attached in the end of the email.

Thank you very much!

Hi,

looks like the command define darkmatter chi psi is actually ignored.

Here is a patch which should solve the problem (hoping formatting --number of space-- will not be modifed):

                 if not self._dm_candidate:

If you can send me your model on my email (<email address hidden>), I would be able to test this.
Otherwise, you can try the patch yourself.

Cheers,

Olivier

Hi Olivier,

Thanks a lot for the patch! Now I found both psi and chi are identified as DM particle. However, Maddm fails when I try "generate relic_density".

Command "generate relic_density" interrupted with error:
KeyError : '1'

Hi,

That means that your UFO model does not follow the normal convention.
So you should contact the author of your model and ask them to fix it.
The problem is that some coupling are defined to a coupling order named "1"
but that name for coupling order is not defined in couplings_order.py
(actually that name itself is not valid since any name should start by a letter since those are used as python variable)

Cheers,

Olivier
