Spin dependence of the masses of heavy baryons.

Recently, Falk [1] has proposed that there exist two undiscovered heavy baryons: a Σc(2380) that decays radiatively to the Λc, and a Σb(5760) that decays radiatively to the Λb. In this note I use the systematics of the spin-dependent forces between quarks to argue against the existence of these two new states. The same ideas suggest that two of the proposed… (More)
