In the present paper we discussed light scalar sgoldstino in context of low scale SUSY breaking. We analyzed electromagnetic sector of interaction of sgoldstino with SM. We also took into account the impact on this interaction of the admixture of lightest MSSM Higgs scalar in the sgoldstino state. The signal rate of rare sgoldstino decays into SM particles at CERN electron beam dump experiment NA64 for the scalar sgoldstino has been estimated. We used expected signal rate to obtain some regions of sgoldstino parameter space (sgoldstino mass and SUSY breaking scale √F).
