Exotic ΩΩ dibaryon states in a molecular picture

We investigate the exotic Omega Omega dibaryon states with JP = 0(+) and 2(+) and in a molecular picture. We construct a tensor molecular interpolating current and calculate the two-point correlation function within the method of QCD sum rules. Our calculations indicate that the masses of the scalar and tensor dibaryon states are m(Omega Omega,0+) = (3.33 +/- 0.51) GeV and 3(Omega Omega,2+) = (3.15 +/- 0.33)GeV, respectively, which are below the 2m(Omega) threshold. Within error, these results do not negate the existence of loosely bound molecular Omega Omega dibaryon states. These exotic strangeness S = -6 and and doubly-charged Omega Omega dibaryons, if they exist, may be identified in heavy-ion collision processes in the future.

Automated summary

The study indicates the existence of exotic ΩΩ dibaryon states in a molecular picture with masses below the 2m(Ω) threshold. They may potentially be identified in heavy-ion collision processes.
