摘要：

A color-sextet assignment for the b quark increases the strength of the linear confining potential by a factor (52)12 over the triplet assignment. This accounts for the observed ′- mass splitting and the leptonic decay rate. The least massive (m∼5 GeV) fermion and the least massive boson containing one b quark are then potentially absolutely stable hadrons. Color-sextet quarks are suggested by extended supergravity. © 1979 The American Physical Society.
