有效Kbar-N相互作用和手征对称性的作用

Effective Kbar N interaction and role of chiral symmetry

Tetsuo Hyodo, Wolfram Weise

摘要:

通过推导有效单道KbarKN势,研究了手征SU(3)对称性在K介子-核子唯象中的作用。结果表明,π-Σ相互作用具有很强的吸引力,并且对λ(1405)共振的结构起着重要的作用。讨论了少体K介子核有效势的含义。

英文摘要:

We study the consequence of chiral SU(3) symmetry in the kaon-nucleon phenomenology, by deriving the effective single-channel KbarK N potential. It turns out that the pi Sigma interaction is strongly attractive and plays an important role for the structure of the Lambda(1405) resonance. We discuss the implication of effective potential for the few-body kaonic nuclei.
