摘要：

Using our present knowledge on effective hadronic theories, short-distance QCD information, the 1/N-C expansion, analyticity and unitarity, we derive an expression for the pion form factor, in terms of m(pi), m(kappa), M-rho and f(pi). This parameter-free prediction provides a surprisingly good description of the experimental data up to energies of the order of 1 GeV. (C) 1997 Published by Elsevier Science B.V.
