Hi Florian,

This is an issue regarding the definition of photon-Z mixing matrix in SARAH_PATH/Models/parameters.m file.
The matrix ZZ in SARAH_PATH/Model/parameters.m is matching with the first matrix in eq. 5.16 in the
manual hep-ph/arxiv:0806.0538 . But it seems eq. 5.16 is inconsistent with eq. 5.11, 5.14, 5.15 in the manual.
I am telling this with reference to the way the different basis and mixing matrix has been implemented just
above eq. 5.16 and also in SM.m file in SARAH_PATH/Models/SM folder. I am interpreting them following
eq. 5.11(replacing 2 in the exponent with T).
I also think that the components of a matrix in SARAH is written following the standard convention of
mathematica.

I am using the version 4.10.1.

Yes, it seems that you are correct. There are unfortunately still quite some typos in the manual.

Cheers,
Florian
