Electron and neutron electric dipole moments in the focus point scenario of the supergravity model

Abstract

We estimate the electron and neutron electric dipole moments in the focus point scenario of the minimal SUGRA model corresponding to large sfermion masses and moderate to large $\mathrm{tan}\ensuremath{\beta}.$ There is a viable region of moderate fine-tuning in the parameter space, around $\mathrm{tan}\ensuremath{\beta}\ensuremath{\simeq}5,$ where the experimental limits on these electric dipole moments can be satisfied without assuming unnaturally small phase angles. But the fine-tuning constraints become more severe for $\mathrm{tan}\ensuremath{\beta}>10.$
