CP Violation in the Width Difference of the Scalar Electron Decay due to Complex Gaugino Masses

Abstract

We calculate the width difference of the scalar electron decay, $\Gamma ({\tilde{e}}_L\to e_L\omega )-\Gamma ({\overline{\stackrel{~}{e}}}_L\to {\bar{e}}_L\omega )$ in the softly broken supersymmetrized standard model. The CP asymmetry is assumed to arise from the complex gaugino masses. Even in limit that the electron mass $m_e$ is vanishing, the difference can be of the order of $\alpha$.
