Are there any narrow K−-nuclear states?

Abstract We performed self-consistent calculations of K − -nuclear quasi-bound states using a single-nucleon K − optical potential derived from chiral meson–baryon coupled-channel interaction models, supplemented by a phenomenological K − multinucleon potential introduced recently to achieve good fits to kaonic atom data [1] . Our calculations show that the effect of K − multinucleon interactions on K − widths in nuclei is decisive. The resulting widths are considerably larger than corresponding binding energies. Moreover, when the density dependence of the K − -multinucleon interactions derived in the fits of kaonic atoms is extended to the nuclear interior, the only two models acceptable after imposing as additional constraint the single-nucleon fraction of K − absorption at rest do not yield any kaonic nuclear bound state in majority of considered nuclei.
