Abstract

We review the influence of lepton flavour violation (LFV) on the production processes e+e- -> ~chi+i ~chi-j at the International Linear Collider (ILC) with longitudinal e+ and e- beam polarizations in the framework of the Minimal Supersymmetric Standard Model (MSSM). The t-channel sneutrino exchange contribution to the processes e+e- -> ~chi+i ~chi-j is modified in the case of LFV, as the sneutrino mass eigenstates have no definite flavour, and therefore more than one sneutrino can contribute. This influence can alter the cross section sigma(e+e- -> ~chi+1 ~chi-1) by a factor of 2 or more when varying the LFV mixing angles, in accordance with the restrictions due to the current limits on rare lepton decays. Hence, the inclusion of LFV parameters can be important when deducing the underlying model parameters from measured observables such as sigma(e+e- -> ~chi+1 ~chi-1).
