Highly Influential

We investigate the relations that must hold among baryonic Isgur-Wise functions ηi in the large-Nc limit from unitarity constraints, and compare to those found by Chow using the Skyrme model [or SU(4)]. Given the exponential dropoff of the ηi away from threshold, unitarity requires only that the usual normalization conditions hold at w = 1, and that η = η1… (More)
