Abstract

We make a theoretical study of the three-body system composed of K̄∗B¯∗B¯∗ and K̄∗B¯B¯∗ to look for possible bound states, which could be associated to mesonic resonances of very exotic nature, containing open strange and double-bottom flavors. The three-body interaction is evaluated by using the fixed center approach to the Faddeev equations where the B¯∗B¯∗ or B¯B¯∗ is bound forming an I(JP)=0(1+) state, as it was found in previous works, and the third particle, the K̄∗, of much smaller mass, interacts with the components of the cluster. We obtain bound states for all the channels considered: spin J=0, 1, and 2, all of them with isospin I=1/2 and negative parity.
