核相互作用:手性图像

Nuclear Interactions: The Chiral Picture

M. R. Robilotta

摘要:

本文综述了两核子力和三核子力的两π交换分量的手征展开,并讨论了预测的层次结构。我们发现标量-等腰中心势的强度太大,与对称性的预期不符。通过研究核子标量形状因子可以理解这种效应的原因。

英文摘要:

Chiral expansions of the two-pion exchange components of both two- and three-nucleon forces are reviewed and a discussion is made of the predicted pattern of hierarchies. The strength of the scalar-isoscalar central potential is found to be too large and to defy expectations from the symmetry. The causes of this effect can be understood by studying the nucleon scalar form factor.
