Hi,

If you do not like the parametrization of the 2HDM model that is shipped inside MGaMC, my advise is that you code in Feynrules,
the lagrangian in your favorite representation (or check if such model is already avaible online).

Cheers,

Hi Rouchad,
                              You can use the model available in the FeynRules website : http://feynrules.irmp.ucl.ac.be/wiki/2HDM

Hi Rouchad,
                            you have to write a restriction file for type I 2HDM like the restriction file for type II , available in the link http://feynrules.irmp.ucl.ac.be/attachment/wiki/2HDM/typeIItbeta.rst

If you need any further info, Please let me know.

Shiba

Hello Shiba;
THnak you so much for your advice i will try it but i still need 2HDM.fr script For Thats.

Hi Rouchad,
                         you only need a restriction file for type I 2HDM. You can use all other .fr files for the model available for 2HDM.
While loading the model files in Mathematica, you have to load that restriction file along with .fr files available in the Feynrules.
Hope, it is clear. If not, please let me know.

Regards,
Shiba

Hello SHiba;
I understand its good idea but i can't found other .fr files for 2HDM.

Are they not inside the file: 2HDM.tar.gz:
of the page:
