强子原子的核介质效应

Nuclear medium effects from hadronic atoms

E. Friedman, A. Gal

摘要:

本文综述了π介子、K介子和S介子原子的研究现状,以及这些强子的介质核相互作用。特别强调了反K介子核物理的最新发展,通过拟合K^-原子数据,在核物质中出现了150-200 MeV量级的强吸引密度相关反K介子核势。这对反K介子准束缚核态、奇异强子物质的组成以及自束缚强子系统中的K介子凝聚都有有趣的影响。

英文摘要:

The state of the art in the study of pionic, kaonic and Sigmionic atoms, along with the in-medium nuclear interactions deduced for these hadrons, is reviewed. A special emphasis is placed on recent developments in antikaon-nuclear physics, where a strongly attractive density dependent antikaon-nuclear potential of order 150-200 MeV in nuclear matter emerges by fitting K^- atom data. This has interesting repercussions on antikaon quasibound nuclear states, on the composition of strange hadronic matter and on kaon condensation in self bound hadronic systems.
