Revisiting electroweak baryogenesis in context of cancelation scenario   in the MSSM
  We study electric dipole moment bounds on CP-violating phases in the MSSM with special emphasis on the cancelation scenario. We find that in the range favored by electroweak baryogenesis ({\it i.e.,} $|\mu|\simeq M_1$ or $|\mu|\simeq M_2$), $\sin [\theta_\mu+\theta_{M_1}]$ can be as large as ${\cal O}(1)$, even for slepton masses below 500 GeV. Such large values of the phases promise a successful electroweak baryogenesis. We also discuss the possibility of large CP-odd effects at a linear collider.
