Hi,
I am trying to implement a pMSSM-like model, where CP violation is allowed. This would result in a possible 7 additional phases (M_1, M_2, M_3, A_t, A_b, A_tau and mu). However, we can use a U(1) transformation to rotate one of these phases away. (In the full MSSM there are two of these redundancies, equivalent Peccei-Quinn (P) and R symmetries in various papers.)
This redundancy would imply that the observables are invariant under this transformation. However, when I try to implement this in SPheno, I get different results for the original and transformed input (by a factor of ~2). We do see that one of the imaginary parts is indeed 0 after the transformation. I have tried to use SARAH to find out the origin of the difference, but without succes.
Therefore my question is: is this redundancy already used somewhere, so that we are now trying to implement it a second time? Or could something else be going wrong?
Thank you for any help!
