SUSY Ward identities in N=1 SYM theory on the lattice

Abstract The SUSY Ward identities (WIs) for the N=1 SU(2) SUSY Yang Mills theory discretized on the lattice with Wilson fermions (gluinos) are considered. The study is performed in the framework of a Monte Carlo simulation of the model with light dynamical gluinos. The renormalization and mixing constants of the lattice SUSY current ZS and ZT and the additively renormalized gluino mass mS are unknown parameters of the SUSY WIs. Using suitable on-shell combinations of the WIs, the ratios ZT/ZS and mS/ZS are determined non-perturbatively at one value of the coupling constant g0 and two values of the hopping parameter κ.
