摘要：

We observe that the Hamiltonian H = (sic)(2), where (sic) is the flat 4d Dirac operator in a self-dual gauge background, is supersymmetric, admitting 4 different real supercharges. A generalization of this model to the motion on a curved conformally flat 4d manifold exists. For an Abelian self-dual background, the corresponding Lagrangian can be derived from known harmonic superspace expressions. (C) 2010 Elsevier B.V. All rights reserved.
