Overview of Antikaon-Nuclear Theory and Phenomenology
Avraham Gal
Abstract
Experimental evidence for antikaon-nuclear quasibound states is briefly reviewed. Theoretical and phenomenological arguments for and against deep antikaon-nucleus potentials which might allow for narrow quasibound states are reviewed, with recent calculations suggesting widths larger than 100 MeV for binding energy smaller than 100 MeV. Results of RMF calculations that provide a lower limit of 50+/-10 MeV for the width of deeply bound states are discussed.
