摘要：
New universality appears for the baryon Isgur-Wise form factor in the large Nc limit. It is found that the semileptonic Λb→Λc and b(*)→c(*) decays are described by the same form factor, which can be calculated analytically. In the exact chiral SU(3) limit, the same form factor is applicable to semileptonic Ωb(*)→Ωc(*) decays. © 1995 The American Physical Society.
