A Measurement of the Form Factors of Light Pseudoscalar Mesons at a Large Momentum Transfer

Abstract

Using the CLEO-II detector, we have studied the exclusive two-photon production of the light pseudoscalar mesons in a single tagged mode. We report on a preliminary measurement of the ${\pi }^0$, $\eta$ and ${\eta }^{\prime }$ electromagnetic form factors in the $Q^2$ region from 2 ${(GeV/c)}^2$ to 20 ${(GeV/c)}^2$.}
