摘要：

In the limit of infinitely heavy quark masses, we derive upper and lower bounds for the Isgur-Wise form factor in the physical region relevant to BBAR-->Dl-nu-l and BBAR-->D*l-nu-l decays. The bounds obtained cast serious doubts on the reliability of the determination of \V(cb)\ made from model fits to the present existing data.
