Hi Florian,

I am using SARAH to calculate one-loop RGEs for THDM-III. However, in the calculation, the couplings Lambda5, Lambda6, and Lambda7 (quartic couplings for the Higgses) are automatically treated as real, even though they should be complex by default according to the parameters.m file. Is there a simple way to treat them as complex in CalcRGEs[] without manually define the real and imaginary parts?

Thanks in advance.

Cheers,
Ruihao

Hi,
unfortunately, the RGE routines for non-SUSY models are implemented so far under the assumption that the quartics are real. I haven't had time in the past to generalise this.

Cheers,
Florian
