Abstract

The possibility of cancellation between different contributions to de, dn and dHg is reconsidered with special emphasis on the region that is phenomenologically interesting (intermediate values of tanβ and sub-TeV sfermion masses). It is found that in the range favored by electroweak baryogenesis (i.e., |μ|M1 or |μ|M2), sin[θμ+θM1]1 can be compatible with the EDM bounds even for slepton masses below 500 GeV. Such large values of the phases promise a successful electroweak baryogenesis. The possibility of large CP-odd effects at linear collider is also discussed.
