Baryon-Baryon Interactions and the Eightfold Way

The deuteron is shown to belong to a ten-dimensional irreducible representation of the group $\mathrm{SU}\left(3\right)\mathrm{}$ in the symmetry scheme called the eightfold way. The baryon-baryon states, which together with the deuteron comprise this supermultiplet, are studied. Data are discussed which favor the existence of some of these states, and the masses of the remaining states are estimated.
