Resumo: In a previous work we applied a discrete symmetry (Z' 2) in order to light fermions acquire mass only at one loop level. This symmetry and the assumption of alignment between fermions and sfermions allow us to avoid FCNC problems. Here a more general hypothesis of flavor mixing in the sfermion sector of MSSM is considered and we show that the s quark is heavier than u,d quarks due to different content of sfermions contributions. Our results are in agreement with the experimental constraint on the values of sfermions masses.
