Abstract
We discuss the possibility that a narrow peak found recently in the ( pi +, pi -) reaction at Tpi =50 MeV could be a signal from an NN-decoupled dibaryon with quantum numbers JP, T=0-, 0. We classify the possible six-quark states with the given quantum numbers in the framework of the nonrelativistic constituent quark model. The 'mass' of the lowest possible state (s5p) is calculated with and without chiral interactions.Keywords
