The prototype of a nuclear cluster, K−pp, has been investigated using effective potentials based on chiral SU(3) dynamics. Variational calculation shows a bound state solution with shallow binding energy and broad mesonic decay width . The pair in the K−pp system exhibits a similar structure as the Λ(1405). We have also estimated the dispersive correction, p-wave interaction, and two-nucleon absorption width.
