Preliminary Results on gamma gamma -> Ks K pi from CLEO
Abstract
We analyzed 13.8 fb^{-1} of the integrated e+e- luminosity collected at 10.6 GeV center-of-mass energy with the CLEO II and II.V detectors to study exclusive two-photon production of single hadronic resonances. We searched for hadrons decaying into Ks K pi when both leptons remain undetected. In this analysis we studied the detection efficiency and evaluated systematic errors using independent data samples. We estimated 90% CL upper limits on the products of the two-photon partial widths of (pseudo)scalar hadrons with masses below 1.7 GeV/c2 and their branching fractions into Ks K pi. Our preliminary results are marginally consistent with the first observation of eta(1440) in two-photon collisions by the L3 experiment.
