Check parameters reading from param_card - MG5

Hi,

> I would like to know if there is a way to control the correct reading of the param_card ?

The reading is the reading, they are no control on that step.

Now depend what your problem is.
If you miss some standard model value then you can use the function “update missing”.
If your problem is a SLHA1 vs SLHA2. Then you need to use one converter between those two format.

Also not that various model in our code have restriction of validity (the default model assumes that all the left/right particles are degenerate in mass for example)

Cheers,

Olivier

Hi Olivier and thanks for your quick answer,

My problem is that I get some surprising values for the cross-section of my process and I do not know yet what is the problem. I wanted to be sure that the problem doesn't come from a reading problem of the parameter card, and this is the reason why I wanted to generate a list of all the parameters that MG truly use (after reading) to be sure that every value match with the correct parameter in MG.

I don't use one of the default models, I use a MSSM model including Non minimal flavor violation (generated with SARAH).

If you have any idea on how I can check this please let me know, if not no problem I will try something else.

In any case thanks again for your help,
Cheers,
Jordan.

Thanks Olivier Mattelaer, that solved my question.
