[Flexiblesusy] Complex mixing matrices in MSSMCPV models

[Carl Martin Fevang]

To whom it may concern,


I am a Master's student of theoretical physics that the University in 
Oslo and am currently using FlexibleSUSY for my Master's thesis under 
the supervision of prof. Are Raklev. I have a question about the MSSMCPV 
and CMSSMCPV models currently shipped with the FlexibleSUSY 2.8.0 
release. Specifically, I am generating spectra for complex MSSM 
scenarios where mu takes an arbitrary complex phase. The generated 
output SLHA files do not seem to output the imaginary parts of the 
mixing matrices, apart for the neutralino mixing matrices when the 
positive majorana flag is turned on.

I had a dig in the code, and am wondering if the correct way to add the 
imaginary parts would be to add a line like

slha_io.set_block_imag("IMDSQMIX",LOCALPHYSICAL(ZD),"ZD");

after line 374 in CMSSMCPV_slha_io.cpp for instance?

Preliminarily it seems to yield reasonable results, but I am wondering 
whether I there is something I have misunderstood, and whether there is 
a built-in or cleaner solution?


Thank you in advance for your help.

Best regards,

Carl Martin Fevang
