Abstract: Searches at the LHC of lepton flavour violation LFV in slepton decays canindirectly test both type-I and II seesaw mechanisms. Assuming universalflavour-blind boundary conditions, LFV in the neutrino sector is related to LFVin the slepton sector by means of the renormalization group equations. Ratiosof LFV slepton decay rates result to be a very effective way to extract theimprint left by the neutrino sector. Some neutrino scenarios within the type-Iseesaw mechanism are studied. Moreover, for both type-I and II seesawmechanisms, a scan over the minimal supergravity parameter space is performedto estimate how large LFV slepton decay rates can be, while respecting currentlow-energy constraints.
