摘要：
我们目前的结果，我们的模拟N=1超对称杨-米尔斯理论的晶格。在比以前更细的晶格间距下得到了胶子-胶粒子、a-eta-prime、a-f0介子和标量胶球的质量，并对胶子质量的消失进行了外推。计算采用了不同程度的粗涂抹。的统计精度，以及控制有限尺寸效应和晶格伪影比以前的调查。考虑到统计和系统的不确定性，我们的计算中的费米子和玻色子态的质量的外推到消失的胶子质量是一致的形成简并超多重态。
英文摘要：
We present the current results of our simulations of N=1 supersymmetric Yang-Mills theory on a lattice. The masses of the gluino-glue particle, the a-eta-prime, the a-f0 meson, and the scalar glueball are obtained at finer lattice spacing than before, and extrapolations towards vanishing gluino mass are made. The calculations employ different levels of stout smearing. The statistical accuracy as well as the control of finite size effects and lattice artefacts are better than in previous investigations. Taking the statistical and systematic uncertainties into account, the extrapolations towards vanishing gluino mass of the masses of the fermionic and bosonic states in our present calculations are consistent with the formation of degenerate supermultiplets.
