Overview of Antikaon-Nuclear Quasi-Bound States

Abstract

Experimental evidence for antikaon-nuclear quasi-bound states is briefly reviewed. Theoretical and phenomenological arguments for and against the existence of such states are considered, based on constructing antikaon-nuclear optical potentials from various sources. Results of RMF calculations that provide a lower limit of Gamma(antikaon) = 50 +/- 10 MeV on the width of antikaon-nuclear quasi-bound states are discussed.
