Complex Singlet Model

[jmcdowall]

Hi Florian,

I'm attempting to implement a complex singlet extension of the SM in SARAH 4.8.6 for use with FlexibleSUSY but i'm having some difficulty when it comes to calculating loop corrections. The particular model i am interested in is from this paper, https://arxiv.org/abs/1411.4048. When i use CalcLoopCorrections[EWSB] i bump into the following error,

Code: Select all

"The first two levels of {{H0,{v,1/Sqrt[2]},{Ah,I/Sqrt[2]},{phih,1/Sqrt[2]}},{CS0,{vevS,1/Sqrt[2]},{veva,I/Sqrt[2]},{phia,I/Sqrt[2]},{phis,1/Sqrt[2]}}} cannot be transposed"

I seems that it can't transpose the VEV lists as it contains elements of unequal length but i'm not quite sure how to get around this problem.

I've attached the SARAH model files for you to look at, any help you could give me would be greatly appreciated.

Thanks,
John McDowall

Hi,

I guess you need to define an imaginary part also for the SM VEV. You can set it later to zero in the numerical calculations (if you are sure that it won't get induced by the complex singlet VEV).
