how to isolate specific wilson coefficients

Asked by Jack

Hi, I'm trying to run a simulation with only c9 and c10 (as used in this paper on page 4: https://arxiv.org/pdf/2101.04709.pdf).

I've been using the smeftsim package and trying to edit the parameter card, but there doesn't seem to be anything corresponding to this - is that using a different basis? And Would I need wcxf (https://github.com/wcxf) to convert between them?

Any help would be great, I'm not quite sure if what I'm doing is at all in the right direction

Hi,

I guess that you should contact the author of the model to ask them on which parameter are controlled via the param_card.
Otherwise, I can only guess (as you) how to do it.

Cheers,

Olivier
