Abstract

Resonance formation has been observed in tagged two photon collisions. Since there is no corresponding signal in the untagged data these resonances have been interpreted as having J=1. Assigning the signal at a mass of ∼1.4 GeV/c2 to the f1(1420), the product of the branching fraction and the two-photon width has been determined to be {Mathematical expression}
