Abstract

The spectrum of excited \mathrm\ensuremathΛ_Q-type heavy baryons is considered in the large N_c limit. The universal form factors for \mathrm\ensuremathΛ_b semileptonic decay to excited charmed baryons are calculated in the large N_c limit. We find that the Bjorken sum rule (for the slope of the Isgur-Wise function) and Voloshin sum rule (for the mass of the light degrees of freedom) are saturated by the first doublet of excited \mathrm\ensuremathΛ_Q states.
