We study the constraints of the CP violation in the muon g − 2 preferred region of the minimal supersymmetric standard model assuming a universal slepton masses within first two generations. We present two particular scenarios where the g − 2 anomaly is predicted within 2 σ level mainly through the chargino loop or the bino loop. We found that for both cases the electron EDM experiment already highly constrained the CP phase of the parameters: either the Arg[μM1] or Arg[μM2] should be smaller than O(2-3)×10−5. If the muon g − 2 anomaly is explained by the MSSM, a particular SUSY breaking mechanism is needed to guarantee the small CP phase of SUSY parameters. Otherwise, a tuning of O(10−5) is needed to cancel the phase in a general CP violated SUSY model.
