abstract
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 $m_\pi, m_K, M_\rho$ 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.
