我们给出了2 + 1味QCD状态方程的完整结果。所有的系统学都被控制，夸克质量被设置为它们的物理值，并进行连续统外推。这扩展了我们先前的研究（Aoki等人，2006 [18]; Borsanyi等人，2010 [14]）到更精细的晶格，并且现在包括具有N-t = 6、8、10、12直到N-t = 16的系综。我们使用了一个Symanzik改进的规范和stout-link改进的交错费米子作用量。我们的发现证实了我们先前的结果。为了便于直接使用我们的状态方程，我们将我们的列表结果提供给下载[33]。(C)2014作者由爱思唯尔公司出版
We present a full result for the 2 + 1 flavor QCD equation of state. All the systematics are controlled, the quark masses are set to their physical values, and the continuum extrapolation is carried out. This extends our previous studies (Aoki et al., 2006 [18]; Borsanyi et al., 2010 [14]) to even finer lattices and now includes ensembles with N-t = 6, 8, 10, 12 up to N-t = 16. We use a Symanzik improved gauge and a stout-link improved staggered fermion action. Our findings confirm our earlier results. In order to facilitate the direct use of our equation of state we make our tabulated results available for download [33]. (C) 2014 The Authors. Published by Elsevier B.V.
