SLHA files as input files

Asked by MohammadMohammadidoust

Hi!
I am a new user of MadDM/Madgraph and have a question about the input parameters of a model.
I have some SLHA files which are generated by SPheno and I need to calculate the Relic density(DD, ...) of these files. To do this, I first imported the MSSM_SLHA2 model from the models' database, generating relic density(added DD,...) and making an output directory. As regular, a param_card.dat file Is created in the Cards subdirectory of the output directory. Yet, when I try to replace my own SLHA files with this param_card.dat and launch model I encounter this error:

"""
Command "launch MY_PROCESS_DIR/" interrupted with error:
KeyError : 'id (1,) is not in mass'

"""

my question is :
is this the correct way to use an SLHA file as an input file?

Any advice would be appreciated.

For direct detection we need to have the light quark consider as masssive and therefore their mass need to be included in the param_card.dat.

In a lot of cases, those mass are not included in the spectrum because those param_card are used for High energy collider.
So you either have to add those masses by hand in your SPHENO output, or check if SPHENO has a way to include it.

MG5aMC has a command "update missing" which can update automatically the current param_card to include missing entry.
I do not know if this feature is also present within maddm but this is likely working.
That command need to be enter when you have the question about the card edition/type of run you want to do
(where you likely have entered the path of your SPHENO card)

Cheers,

Olivier
