Question

I'm currently studying at the spectra of some supersymmetric models, and would like to know whether the parameter points I'm looking at are ruled out due to excessive CP violation.

I am using SPheno, which allows me to test my spectra against various other experimental bounds. It provides a Block SPhenoLowEnergy in its SLHA output that has, for example, the predicted branching ratio Bs???, or the anomalous muon g?2.

What's the variable to look for when one colloquially says "ruled out because of CP violation"? How to get it in SPheno (or with any other spectrum generator / event generator, I can switch)? I feel like the answer is obvious but I'm missing the forest for the trees.

Explanation / Answer

Why do you anticipate extra sources of CP violation? Are you using complex Lagrangian parameters? If so, the best experimental limits might be contributions to electric dipole moments, permitted only at three-loops in the SM, and possibly limits on CP violation in the Higgs sector.
