核标量等熵流的次级贡献

Subleading contributions to the nuclear scalar isoscalar currents

Hermann Krebs, Evgeny Epelbaum, Ulf-G. Meißner

摘要:

在手征有效场论的框架下,推广了我们最近对核矢量、轴矢量和赝标流的分析,并利用幺正变换的方法导出了双核子标量流算符的主导单圈修正.我们还表明,在零动量转移的标量电流算符是直接相关的夸克质量依赖的核力。

英文摘要:

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.
