我们研究了晶格上十二味 QCD 的红外共形性。利用对研究连续介质物理有用的高度改进的交错夸克(HISQ)型作用,我们分析了赝标量介子的质量和衰变常数以及矢量介子的质量以及多个晶格间距和费米子质量值的晶格数据。我们的结果与质量异常尺寸 m ∼ 0.4 − 0.5 的共形假设一致。
We study infrared conformality of the twelve-flavor QCD on the lattice. Utilizing the highly improved staggered quarks (HISQ) type action which is useful to study the continuum physics, we analyze the lattice data of the mass and the decay constant of a pseudoscalar meson and the mass of a vector meson as well at several values of lattice spacing and fermion mass. Our result is consistent with the conformal hypothesis for the mass anomalous dimension m ∼ 0.4 − 0.5.
