Abstract
We show that the recent electron-positron colliding-beam experiment at Novosibirsk and -photoproduction experiment at Deutsches Elektronen-Synchrotron yield couplings which are consistent with the predictions of simple SU(2)SU(2) effective Lagrangian theories containing an axial-vector meson. This includes the prediction of the virtual mass dependence of .
