核子-核子散射一圈图的手征有效场论分析

One-loop analysis of nucleon-nucleon scattering in the chiral effective field theory

采用相对论性框架下的手征有效场论,对核子-核子散射的π交换一圈图过程重要圈图进行了计算和分析,即三角图(triangle diagrams)和平面箱图(planar box diagram,简写为pb),并以此为基础进一步分析讨论了核子-核子散射手征有效场论的结构特点,为最终建立一个满意的核力有效场论框架做新的探索.

In this paper we will analyze the important one-loop pion-exchange diagrams for nucleon-nucleon（N-N） scattering in the relativistic framework of chiral effective theory,namely the triangle diagrams and the planar box diagram.On this basis,we wish to further explore the structures of the chiral effective theory in order to contribute to the establishment of a satisfactory effective field theory for nuclear forces.
