论文摘要
我们将最近对核向量，轴向矢量和伪尺度电流进行了分析，并使用单一转化的方法在手性有效场理论的框架内将领先的一环校正推导到两个核子标量电流运算符中。我们还表明，零动量转移的标量电流运算符与核力量的夸克质量依赖性直接相关。
We extend our recent analyses of the nuclear vector, axial-vector and pseudoscalar currents and derive the leading one-loop corrections to the two-nucleon scalar current operator in the framework of chiral effective field theory using the method of unitary transformation. We also show that the scalar current operators at zero momentum transfer are directly related to the quark mass dependence of the nuclear forces.
