Question about VEV

[sgurruti]

Hello,
I have a model implemented in SARAH and exported to SPheno. This model has two VEV's, one of them is an input of the model and the other (the SM-like VEV) apparently is calculated by SPheno or is an internal parameter of the model. I would like to change the value of the SM-like VEV but I don't how to do it. How can I check which of the two mentioned possibilities is really implemented?

Best regards,
Sebastian

Hi,

do you use a low or high-scale input? In a low-scale input, SPheno derives the ew-VEV from the Fermi-Constant. Thus, you can adjust it by adjusting G_F.
