A supersymmetric version of the standard SU(3) ⊗ SU(2) ⊗ U(1) model is contructed in the present paper. The low-energy (≲ 1 TeV) Higgs sector together with two SU(2) doublets H and H′ necessarily contain the neutral singlet G. The Fayet-Iliopoulos D -term induce SUSY breaking. Unification into SUSY SU(5) occurs at high energy. Operators with d = 5 do not lead to fast proton decay because of the absence of the Majorana mass term λ H′ ϵλ H C at the minimum of the low-energy Higgs potential. Operators with d = 6 lead to proton decay with τ p ≈ 10 34 yr . A variety of new particles and interactions appears at energies ≈ 100 GeV in this model (this is typical for models with low-energy SUSY).
