Stable heavy pentaquarks in constituent models
It is shown that standard constituent quark models produce (c¯cqqq) hidden-charm pentaquarks, where c denotes the charmed quark and q a light quark, which lie below the lowest threshold for spontaneous dissociation and thus are stable in the limit where the internal c¯c annihilation is neglected.
