Description

SU(3) breaking in quark masses affects hyperfine energy and configuration mixing in the proposed H dibaryon (a ΛΛ bound state). The hyperfine energy is modified substantially, so that it is much less advantageous than in the SU(3) limit (by about a factor of 3) to recouple the spins of the quarks in two Λ's to form an H. Nonetheless, the H remains an almost pure configuration of the 490-dimensional representation of color-spin SU(6), with a negligible amount of the other possible configuration (189 dimensional) admixed
