Dear Mohamed,

with your command the code is loading by default the model

loop_qcd_qed_sm

and doing on-shell renormalisation.
However, W and Z widths have to be set to zero for consistency, if you set the widths to zero in the param_card it should work.

My suggestion is anyway that you load the model

import model loop_qcd_qed_sm_Gmu

which uses the Gmu scheme for renormalisation, a better option for this process.
You can also directly load

loop_qcd_qed_sm_Gmu-no_widths

so that widths are automatically zero.

Cheers
Davide

Dear Davide,

thank you for your reply

I restarted the process by importing the model loop_qcd_qed_sm_Gmu
and I get the same error message:
