摘要:

我们提出了一个唯象格点量子色动力学计算的框架,该框架利用了胶子和Stout-link Wilson费米子的树级Symanzink改进作用量。我们给出了我们的高效HMC/RHMC算法的细节,并给出了N_f=3重子谱的标度研究。我们发现了一个扩展到a~<0.16fm的标度区域,并得出结论:我们的行为和算法适用于N_f=2+1 QCD的大尺度唯象研究。我们希望这一结论适用于其他类似的行动。

英文摘要:

We present a framework for phenomenological lattice QCD calculations which makes use of a tree level Symanzink improved action for gluons and stout-link Wilson fermions. We give details of our efficient HMC/RHMC algorithm and present a scaling study of the low-lying N_f=3 baryon spectrum. We find a scaling region that extends to a~<0.16fm and conclude that our action and algorithm are suitable for large scale phenomenological investigations of N_f=2+1 QCD. We expect this conclusion to hold for other comparable actions.
