摘要:

本文对$16^3\times 32\times (0.12 {\rm fm})^4$格点上两种夸克动力学味的量子色动力学进行了数值模拟。我们计算了赝标量质量和衰变常数,并研究了它们的手征性质。我们测试我们的数据的一致性与双回路手征微扰理论的预测,这也应该是有效的,因为确切的手征对称性,包括有限的尺寸效应在有限的晶格间距。

英文摘要:

We present numerical simulation of QCD with two dynamical quark flavors described by the overlap fermion action on a $16^3\times 32\times (0.12 {\rm fm})^4$ lattice. We calculate pseudo-scalar masses and decay constants and investigate their chiral properties. We test the consistency of our data with the two-loop chiral perturbation theory predictions, which should also be valid at finite lattice spacings because of the exact chiral symmetry, including the finite size effects.
