contribution to lepton (L)FV decays and EDMs have the advantage, as compared to the corresponding squark sector ones, of being not biased by the SM contribution - nor by the non-supersymmetric seesaw [@seesaw] contribution [@pet]. Experimental limits on LFV decays and EDMs are then a direct probe of the flavour and CP pattern of slepton masses - see e.g. Ref. [@ms1] for a recent collection. From a theoretical perspective, understanding why CP phases and deviations from alignment are so strongly suppressed is one of the major problems of low energy supersymmetry, the [*CP and flavour problem*]{}. On the other hand, precisely because FV decays and EDMs provide strong constraints, they can share some light on the features of the (possibly) supersymmetric extension of the SM.

Indeed, it is well known that even if these CP phases and misalignments were absent - or suppressed enough - from the effective broken supersymmetric theory defined at $M_{Pl}$, they would be generated at low energy by the RGE corrections due to other flavour and CP violating sources already present in the theory, in particular from the Yukawa couplings of heavy states like the right-handed neutrinos of the seesaw model [@bormas] and the Higgs triplets
