Using previously formulated sum rules in the heavy quark limit of QCD, we demonstrate that if the slope ρ2 = −ξ(1) of the Isgur-Wise function ξ(w) attains its lower bound 3 4 , then all the derivatives (−1)Lξ(L)(1) attain their lower bounds (2L + 1)!! 22L , obtained by Le Yaouanc et al. This implies that the IW function is completely determined, given by… CONTINUE READING
