摘要：
Effects of CP violation on the supersymmetric electroweak correction to the anomalous magnetic moment of the muon are investigated with the most general allowed set of CP violating phases in the MSSM. The analysis includes contributions from the chargino and the neutralino exchanges to the muon anomaly. The supersymmetric contributions depend only on specific combinations of CP phases. We analyze the effects of the phases under the EDM constraints and show that large CP violating phases can drastically affect the magnitude of the supersymmetric electroweak contribution to a(mu) and may even affect its overall sign.
