| Scaling study of dynamical smeared-link clover fermions (2008) | |||||||||
Abstract | |||||||||
| 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 down to a lattice cutoff of a^{-1} ~< 1.3 GeV 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.. Comment: 11 pages, 7 figures, aps style | |||||||||
