摘要:

本文报道了四维{ \cal N}=1 SU(2)超Yang-Mills理论的晶格模拟结果.本文研究了8^3 \times 16格点上具有Iwasaki作用量的三种不同质量m=0.2,0.1和0.05的重叠Dirac算符的谱.我们发现,最低特征值分布与随机矩阵理论的预测吻合得很好。此外,凝聚体的质量依赖性几乎是恒定的,这给出了一个干净的手征极限。在手征极限下,我们的结果是< \bar凝聚> r_0 ^3 = 0.63(12),其中r_0是索默标度.

英文摘要:

We report on a lattice simulation result for four-dimensional {\cal N}=1 SU(2) super Yang-Mills theory with the dynamical overlap gluino. We study the spectrum of the overlap Dirac operator at three different gluino masses m=0.2, 0.1 and 0.05 with the Iwasaki action on a 8^3 \times 16 lattice. We find that the lowest eigenvalue distributions are in good agreement with the prediction from the random matrix theory. Moreover the mass dependence of the condensate is almost constant, which gives a clean chiral limit. Our results for the gluino condensate in the chiral limit is < \barψ ψ> r_0^3 = 0.63(12), where r_0 is the Sommer scale.
