标题： World-Line Path Integral Study of Supersymmetry Breaking in the Wess-Zumino Model

摘要： 我们通过世界线路径积分算法研究了格点N=1 Wess-Zumino模型中的超对称破缺。利用基态能量和超对称Ward恒等式来支持有限体积下的预期对称性破缺。讨论了拓扑电荷的非高斯涨落，并将其与无限体积跃迁联系起来。 显示英文摘要

摘要： We study supersymmetry breaking in the lattice N=1 Wess-Zumino model by the world-line path integral algorithm. The ground state energy and supersymmetric Ward identities are exploited to support the expected symmetry breaking in finite volume. Non-Gaussian fluctuations of the topological charge are discussed and related to the infinite volume transition.
