标题： Accurate hadron spectroscopy on blocked configurations by tadpole-renormalized, clover-improved Wilson quark action

摘要： 我们比较了对于Wilson夸克作用量、clover作用量以及tadpole改进的clover作用量，在阻塞和未阻塞的格点上的淬火hadron能谱。 后一种作用量即使在截止尺度为1/a ~ 500 MeV时，所得的能谱也明显更接近原始的能谱。 显示英文摘要

摘要： We compare the quenched hadron spectrum on blocked and unblocked lattices for the Wilson quark action, the clover action and the tadpole-improved clover action. The latter gives a spectrum markedly closer to the original one, even though the cutoff is 1/a ~ 500 Mev.
