摘要：

In a previous article, it was proved in the framework of the chiral soliton model that the same Isgur-Wise form factor describes the semileptonic Lambda(b)-->Lambda(c) and Sigma(b)((*))-->Sigma(c)((*)) decays in the large N-c limit. It is shown here that this result is in fact independent of the chiral soliton model and is solely the consequence of the spin-flavor SU(4) symmetry which arises in the baryon sector in the large N-c limit.
