Abstract
Supersymmetric SUSY Ward identities are considered for the N=1 SU2 SUSY YangMills theory discretized on the lattice with Wilson fermions gluinos They are used in order to compute nonperturbatively a subtracted gluino mass and the mixing coefficient of the SUSY current The computations were performed at gauge coupling beta=23 and hopping parameter kappa=01925 0194 01955 using the twostep multibosonic dynamicalfermion algorithm Our results are consistent with a scenario where the Ward identities are satisfied up to Oa effects The vanishing of the gluino mass occurs at a value of the hopping parameter which is not fully consistent with the estimate based on the chiral phase transition This suggests that although SUSY restoration appears to occur close to the continuum limit of the lattice theory the results are still affected by significant systematic effects
