f1 (1285) formation in photon-photon fusion reactions
Abstract
We have observed formation of the f1 (1285) in the reaction e+e-→e+e-π+π-η(η→γγ). Its γγ∗ width is determined in several Q2 bins. The γγ coupling parameter for the f1 (1285) is found to be 2.4±0.5±0.5 keV. This value is compared to that for the X (1420), another J=1 state formed in γγ fusion reactions, which may belong to the same meson nonet.
