Özet

In the framework of the recently proposed gluino-axion model, using the effective potential method and taking into account the top-stop as well as the bottom-sbottorn effects, we discuss the CP properties of the lightest Higgs boson, in particular its CP-odd composition, which can offer new opportunities for collider searches. It is found that although the CP-odd composition of the lightest Higgs increases slightly with the inclusion of the sbottorn effects, it never exceeds 0.17% for all values of the renormalization scale Q ranging from top mass to TeV scale.
