  Supersymmetry is a prominent candidate for physics beyond the standard model.
In order to compute the spectrum of supersymmetric theories, we employ
nonperturbative lattice QFT techniques which due to the discretisation of
spacetime violate supersymmetry at finite lattice spacings. Care has to be
taken then to restore supersymmetry in the continuum limit. We discuss a
discretisation of the supersymmetric Nonlinear O(N) Sigma model in two
dimensions and argue that supersymmetry may be restored by finetuning of a
single parameter. Furthermore, we show preliminary results for the vacuum
physics of N = 2 Super-Yang-Mills theory in three dimensions.
