CP violation and scalar lepton flavor oscillation

Lepton flavor violation can be induced in supersymmetry by the mixing of two or more of the leptonic scalar partners, (l) over tilde --> (l) over tilde', where (l) over tilde, (l) over tilde' = (e) over tilde, <(mu)over tilde>, <(tau)over tilde>. 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 (LFV) decays. If the slepton mixing involves all three generations, CP violation from the Cabibbo-Kobayashi-Maskawa phase could lead to asymmetries between the observed LFV decays (l) over tilde --> (l) over tilde' and l --> l'. 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.
