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 havingJ=1. Assigning the signal at a mass of ∼1.4 GeV/c2 to thef 1(1420), the product of the branching fraction and the two-photon width has been determined to be B(f1(1420)→KKˉπ)⋅Γ˜f1(1420)=2.3+1.0−0.9±0.8keV.
