  "abstract": "Recent developments are summarised concerning low-energy KbarN interactions as they relate to the possible existence of antikaon-nuclear quasibound states. An exploratory study of antikaons bound to finite nuclei is performed, with emphasis on the evolution of such states from light to heavy nuclei (A = 16 - 208). The energy dependent, driving attractive KbarN interactions are constructed using the s-wave coupled-channel amplitudes involving the Lambda(1405) and resulting from chiral SU(3) dynamics, plus p-wave amplitudes dominated by the Sigma(1385). Effects of Pauli and short-range correlations are discussed. The decay width induced by K^-NN two-body absorption is estimated and found to be substantial. It is concluded that Kbar-nuclear quasibound states can possibly exist with binding energies ranging from 60 to 100 MeV, but with short life times corresponding to decay widths of the similar magnitudes.",
