Abstract

The lepton-flavor violation (LFV) effect at an e⁺e^- linear collider (LC), in the frame of R-parity violating minimal supersymmetric standard model is studied. We take the R-parity violating processes e⁺e^-→ e^∓μ^± as signal, and define the summation of the two processes as ``experiment'' observable. We find that the cross-section summation can reach \calO(10¹)fb in the parameter space without sneutrino resonance effect(√(s) ∼ m_ν). The summation treatment manifests uniform differential distribution on cosθ, where θ denotes the polar angles of both outgoing e⁺/e^- respectively to incoming electron beam in two signal processes. The uniform feature together with eμ collinearity would help to reduce the SM background dramatically. Consequently we conclude that at a 500 GeV LC with 480 fb^-1 annual luminosity, it's either possible to detect the distinctive R-violating LFV eμ signal, or exclude sneutrino to m_ν>1.1 TeV at 95% CL in the machine's biennial runtime interval.
