Abstract
The prototype of a barK nuclear cluster K − pp has been investigated using effective barKN potentials based on chiral SU3 dynamics Variational calculation shows a bound state solution with shallow binding energy BK − pp = 20±3 MeV and broad mesonic decay width GammabarKNN rightarrow pi Y N=40–70 MeV The barKNI=0 pair in the K − pp system exhibits a similar structure as the Λ1405 We have also estimated the dispersive correction pwave barKN interaction and twonucleon absorption width
