Search For Eta(B) In Two-Photon Events

A search for the pseudoscalar meson eta(b) was performed at LEP II energies with an integrated luminosity of 700pb(-1). The search, done for the decay modes into 4 and 6 charged particles yielded 0 and 1 candidates, respectively. Upper limits on Gamma(gamma gamma)(eta(b)) x BR for both modes of 57 eV and 128 eV were obtained with corresponding limits of 17% and 38% on branching ratios BR(eta(b) -> 4 charged particles) and BR(eta(b) -> 6 charged particles) at a confidence level of 95%. The candidate has a mass of 9.30 +/- 0.04 GeV.
