摘要：
In a numerical Monte Carlo simulation of SU(2) Yang-Mills theory with dynamical gauginos we find evidence for two degenerate ground states at the supersymmetry point corresponding to zero gaugino mass. This is consistent with the expected pattern of spontaneous discrete chiral symmetry breaking Z(4)-->Z(2) caused by gaugino condensation. (C) 1999 Published by Elsevier Science B.V.
