Electromagnetic meson form factors in a covariant Salpeter model

We present a covariant formulation of the Salpeter equation for {ital q{bar q}} states in order to calculate bound-state transitions between mesons. The corresponding Bethe-Salpeter amplitudes are reconstructed from equal-time amplitudes which were obtained in a previous paper by solving the Salpeter equation for a confining plus an instanton-induced interaction. This method is applied to calculate electromagnetic form factors and decay widths of low-lying pseudoscalar and vector mesons, including predictions for CEBAF experiments. We also describe the momentum transfer dependence for the processes {pi}{sup 0},{eta},{eta}{sup {prime}}{r_arrow}{gamma}{gamma}{sup *}.
