Abstract
We study lepton flavour violating decays of neutralinos and sleptons within the Minimal Supersymmetric Standard Model, taking into account the recent bounds on flavour violating lepton decays. Taking the SPS1a' scenario as an example, we show that some of these lepton flavour violating branching ratios of neutralinos and sleptons can be ~5-10%. We study the impact of the lepton flavour violating neutralino and slepton decays on the di-lepton mass distributions measured at LHC. We find that they can result in novel and characteristic edge structures in the distributions. The appearance of these remarkable structures provides a powerful test of supersymmetric lepton flavour violation at LHC.
