dc.description.abstract	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.	pt_BR
