CP Violation and Scalar Lepton Flavor Oscillation

Abstract

Lepton flavor violation can be induced in supersymmetry by the mixing of two or more of the leptonic scalar partners, Krashnikov and Arkani-Hamed et al. pointed out that this effect may be observable at the Next Linear Collider, through slepton pair production with subsequent lepton flavor violating decays. If the slepton mixing involves all three generations, CP violation from the Cabibbo-Kobayashi-Maskawa phase could lead to CP violating asymmetries between the observed LFV decays. We lay down the formalism and give simple expressions for the CP violating asymmetry in the transition probabilities, and consider possible signals at future colliders.
