我们提出了一种利用非微扰 O(a) 改进的威尔逊夸克作用计算双味 QCD 中 kaon 形状因子的方法。为了在 SU(3) 破坏效应的研究中达到百分之几的精度，我们使用一组矩阵元素的双倍比率，从而抵消大部分统计波动和乘法重正化因子。
We present a calculation of the kaon form factors in two-flavor QCD with the non-perturbatively O(a)-improved Wilson quark action. In order to achieve a few percent accuracy in the study of SU(3) breaking effects, we use a set of double ratios of the matrix elements, with which the bulk of the statistical fluctuation and the multiplicative renormalization factors cancel.
