Abstract
We investigate the relations that must hold among baryonic Isgur-Wise functions in the large-N_c limit from unitarity constraints, and compare to those found by Chow using the Skyrme model [or SU(4)]. Given the exponential dropoff of the away from threshold, unitarity requires only that the usual normalization conditions hold at w=1, and that near threshold. Our results are consistent with, but less powerful than, the Skyrme model relations.
