摘要：

We derive optimal bounds on the Isgur-Wise function, taking into account the information about the measured masses of the upsilon poles present in the heavy meson elastic form factor. In the large b-quark mass limit, when the poles move towards the BB threshold, our results approach the bounds originally derived by de Rafael and Taron.
