A new model of supersymmetry between bosons and fermions is proposed, Its representation space is spanned by states with PF symmetry and real energies but the inter-related partner Hamiltonians themselves remain complex and non-Hermitian. The formalism admits vanishing Witten index. (C) 2000 Elsevier Science B.V. All rights reserved.
