Electron and neutron electric dipole moments in the constrained MSSM
Abstract
We analyze the effects of CPviolating phases on the electric dipole moment (EDM) of the electron and neutron in the constrained minimal supersymmetric model. We find that the phases φ_{μ} and φ_{A0} have to be strongly correlated, in particular for small values of the SUSY mass parameters. We calculate the neutron EDM in two different models, the quarkparton model and the chiral quark model. It turns out that the predictions are quite sensitive to the model used. We show parameter regions in the M_{0}M_{1/2} plane which are excluded by considering simultaneously the experimental bounds of both electron and neutron EDM, assuming specific values for the phases φ_{μ} and φ_{A0}.
