摘要:

本文采用改进的源和汇算符,数值研究了具有两个伴随费米子的SU(2)规范理论的光谱观测量。我们详细比较了我们的改进结果与以前的确定使用点源和汇的群众,我们调查在这两种情况下可能的系统性影响。这样的比较使我们能够清楚地评估一个短的时间范围对物理图像的影响,并调查由于有限的空间盒的一些影响。在确认IR共形行为的理论,我们的调查表明,为了使公司的定量预测,有限尺寸效应需要一个更好的处理。

英文摘要:

We present a numerical study of spectroscopic observables in the SU(2) gauge theory with two adjoint fermions using improved source and sink operators. We compare in detail our improved results with previous determinations of masses that used point sources and sinks and we investigate possible systematic effects in both cases. Such comparison enables us to clearly assess the impact of a short temporal extent on the physical picture, and to investigate some effects due to the finite spatial box. While confirming the IR-conformal behaviour of the theory, our investigation shows that in order to make firm quantitative predictions, a better handle on finite size effects is needed.
