摘要：
In this Letter we construct N = (1, 0) and Ar = (1, 1/2) non-singlet Q-deformed supersymmetric U(1) actions in components. We obtain an exact expression for the enhanced supersymmetry action by turning off particular degrees of freedom of the deformation tensor. We analyze the behavior of the action upon restoring weekly some of the deformation parameters, obtaining a non-trivial interaction term between a scalar and the gauge field, breaking the supersymmetry down to N = (1, 0). Additionally, we present the corresponding set of unbroken supersymmetry transformations. We work in harmonic superspace in four Euclidean dimensions. (c) 2006 Elsevier B.V. All rights reserved.
