摘要：We study dynamical supersymmetry breaking and the transition point by non-perturbative lattice
techniques in a class of two-dimensional N
1 Wess-Zumino model. The method is based on
the calculation of rigorous lower bounds on the ground state energy density in the infinite-lattice
limit. Such bounds are useful in the discussion of supersymmetry phase transition. The transition
point is determined with this method and then compared with recent results based on large-scale
Green Function Monte Carlo simulations with good agreement.
