| Abstract;The fine-tuning problem and the stability of the space-time structure are studied for the two-dimensional U(2) lattice gauge model proposed by Cohen et al. The soft supersymmetry breaking mass term is introduced, in order to avoid the infrared divergence for the fermion zero mode. The bosonic zero momentum mode is treated nonperturbatively. The mass counter term in the finite volume is found to vanish in the infinite volume limit, so that the theory is free from the fine-tuning problem. It is pointed out that the supersymmetry plays an important role in stabilizing the space-time structure. |
