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→l', where l,l'=e,μ,τ. 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→l' and bar l→ bar 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. copyright 1997 The American Physical Society
