摘要:

在超对称Yang-Mills理论的数值研究中,超对称沃德恒等式对于寻找跳跃参数的临界值和通过格点离散化研究超对称破缺的大小是很有价值的。在这篇文章中,我们提出了一个改进的方法,数值分析的超对称沃德恒等式,它考虑到各种观测量之间的相关性。本文首次对规范群SU(3)下的$\mathcal{N}=1$超对称Yang-Mills理论中的超对称沃德恒等式进行了完整的分析。结果表明,随着$O(a^2)$朝向连续极限,晶格伪影缩放到零,与理论预期一致。

英文摘要:

In numerical investigations of supersymmetric Yang-Mills theory on a lattice, the supersymmetric Ward identities are valuable for finding the critical value of the hopping parameter and for examining the size of supersymmetry breaking by the lattice discretisation. In this article we present an improved method for the numerical analysis of supersymmetric Ward identities, which takes into account the correlations between the various observables involved. We present the first complete analysis of supersymmetric Ward identities in $\mathcal{N}=1$ supersymmetric Yang-Mills theory with gauge group SU(3). The results show that lattice artefacts scale to zero as $O(a^2)$ towards the continuum limit in agreement with theoretical expectations.
