Resumen
- We study the possible existence of bound states of three Ω_(bbb) baryons. We consider onlySwave interactions and we start from recent lattice QCD results which give a strongly attractive potential between two Ω_(bbb) baryons in the ^(1)S_(0) channel. We analyze different scenarios. At baryonic level, the Ω_(bbb)Ω_(bbb) interaction could be understood to be basically spin-independent, so that the two contributing channels, ^(1)S_(0) and ^(5)S_(2), would have a very similar interaction. This baryonic analysis leads to the existence of bound states in the three-body system. At thequark level, repulsive effects would appear in the ^(5)S_(2)channel, making it more repulsive than the1S0channel. We study the effect of such repulsion.
