3. T bbb : A three B -meson bound state / Garcilazo, H. ; Valcarce, A.
By solving exactly the Faddeev equations for the bound-state problem of three mesons, we demonstrate that current theoretical predictions pointing to the existence of a deeply-bound doubly bottom axial vector tetraquark lead to the existence of a unique bound state of three B mesons. [...]

6. Stable heavy pentaquarks in constituent models / Richard, J.-M. ; Valcarce, A. ; Vijande, J.
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. [...]
