标题： Meson correlators in a finite volume near the chiral limit

摘要： 我们报道了在有限体积中介子相关函数计算的结果。该计算是在接近奇点的淬火近似下（小至 Mq = 2.6 MeV）使用重叠费米子完成的。对于这些小夸克质量，标量和伪标量相关函数可以用几百个本征模很好地近似。连接和非连接相关函数的结果与淬火手征微扰理论的理论预测进行了比较。 显示英文摘要

摘要： We report on the results of our calculation of meson correlators in a finite volume. The calculation is carried out in the quenched approximation near the chiral limit (down to Mq = 2.6 MeV) using the overlap fermion. For these small quark masses, the scalar and pseudo-scalar correlators are well approximated with a few hundred eigenmodes. The results for both connected and disconnected correlators are compared with the theoretical predictions of quenched chiral perturbation theory.
