Tribaryons with lattice QCD and one-boson exchange potentials

Motivated by the existence of two-body hadronic molecules composed of ωω, ωcccωccc, and ωbbbωbbb predicted by lattice QCD simulations, we use the Gaussian expansion method to investigate whether three-body systems composed of ωωω, ωcccωcccωccc, and ωbbbωbbbωbbb can bind with the two-body S01 interactions provided by lattice QCD. Our results show that none of the three-body systems bind. On the other hand, we find that with the one-boson exchange potentials the ωωω system develops a bound state, for which the S25 interaction plays an important role. Our studies support the existence of the 32+ ωωω bound state and the nonexistence of the 32+ ωcccωcccωccc and ωbbbωbbbωbbb bound states, due to the suppressed S25 interactions in heavier systems.
