利用畴壁费米子在手征极限下的晶格超杨-米尔斯
Lattice super-Yang-Mills using domain wall fermions in the chiral limit
摘要：
格点N=1超杨-米尔斯理论使用金斯帕-威尔逊费米子公式化，提供了连续统理论的严格的非微扰定义，当格点间距减少到零时，不需要微调。畴壁费米子是实现这一点的一个显式方案，利用它们，我们对规范群SU（2）的理论进行了大规模的蒙特卡罗模拟。我们测量了几种畴壁间距L_s值、四维晶格体积和两种规范耦合值下的高吉诺凝聚、静态势、克罗伊茨比和剩余质量。有了这些数据，我们能够外推的高根诺凝聚体的手征极限，表示它在物理单位，并建立重要的基准，为未来的研究超杨米尔斯的晶格。
英文摘要：
Lattice N=1 super-Yang-Mills theory formulated using Ginsparg-Wilson fermions provides a rigorous non-perturbative definition of the continuum theory that requires no fine-tuning as the lattice spacing is reduced to zero. Domain wall fermions are one explicit scheme for achieving this and using them we have performed large-scale Monte Carlo simulations of the theory for gauge group SU(2). We have measured the gaugino condensate, static potential, Creutz ratios and residual mass for several values of the domain wall separation L_s, four-dimensional lattice volume, and two values of the gauge coupling. With this data we are able to extrapolate the gaugino condensate to the chiral limit, to express it in physical units, and to establish important benchmarks for future studies of super-Yang-Mills on the lattice.
