In-medium K̄ interactions and bound states
Abstract
Correct treatment of subthreshold K̄ N dynamics is mandatory in K− -atom and K̄ -nuclear bound-state calculations, as demonstrated by using in-medium chirally-based models of K̄ N interactions. Recent studies of kaonic atom data reveal appreciable multi-nucleon contributions. K̄ -nuclear widths larger than 50 MeV are anticipated.
