Abstract

We consider the interplay of the pentaquark states and strange tetraquark states in the decay Λb0→K−J/ψp\Lambda^0_b\to K^-J/\psi p. Possible existence of (cscˉuˉcs\bar c\bar u)-states is taken up and their manifestation in the K−J/ψK^-J/\psi -channel is discussed. It is emphasised that these exotic mesons can imitate broad bumps in the in the pJ/ψpJ/\psi -channel.
