SUPERSYMMETRIC GAUGE QUANTUM-MECHANICS - SUPERFIELD DESCRIPTION

The superfield formulation of a class of SUSY quantum-mechanical systems connected with effective (0 + 1)-dimensional hamiltonians of supersymmetric gauge theories is proposed. These provide us with supersymmetric d = 1 sigma-models of a new type: their bosonic target manifolds are 3m-dimensional (m is an integer) with the metrics of a special form, and they enjoy N = 2 supersymmetry. They are constructed (in a peculiar way, specific for d = 1) from d = 4 vector gauge supermultiplets reduced to 0 + 1 dimensions. A reasonable generalization of these models to higher dimensions is absent.
