摘要：

The SIGMA(c)* - SIGMA(c) and SIGMA(b)* - SIGMA(b) hyperfine mass splittings are computed in the Skyrme model. The hyperfine splittings are suppressed by both 1/N(c) and by I/m(Q), where N(c) is the number of colors and m(Q) is the mass of the heavy quark. The SIGMA(c), SIGMA(c)*, SIGMA(b), SIGMA(b)*, and LAMBDAb masses are predicted in terms of the known values of the LAMBDA(c), D, D*, B and B* masses.
