Abstract :
In the context of the lattice regularization of the four-dimensional image supersymmetric Yang–Mills theory (4D image SYM), we formulate a generalized BRS transformation that treats the gauge, supersymmetry (SUSY), translation and axial image (image) transformations in a unified way. A resultant Slavnov–Taylor identity or the Zinn-Justin equation gives rise to a strong constraint on the quantum continuum limit of symmetry breaking terms with the lattice regularization. By analyzing the implications of the constraint on operator-mixing coefficients in the SUSY and the image Ward–Takahashi (WT) identities, we prove to all orders of perturbation theory in the continuum limit that, (i) the chiral symmetric limit implies the supersymmetric limit and, (ii) a three-fermion operator that might potentially give rise to an exotic breaking of the SUSY WT identity does not emerge. In previous literature, only a naive or incomplete treatment on these points can be found. Our results provide a solid theoretical basis for lattice formulations of the 4D image SYM.
