Abstract

We construct N = 1 supersymmetric nonlocal theories in four dimension. We discuss higher derivative extensions of chiral and vector super fields, and write down generic forms of Kahler potential and superpotential up to quadratic order. We derive the condition in which an auxiliary field remains non-dynamical, and the dynamical scalars and fermions are free from the ghost degrees of freedom. We also investigate the nonlocal effects on the supersymmetry breaking and find that supertrace (mass) formula is significantly modified even at the tree level.
