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_gammagamma(eta_b)*BR for both modes of 57eV and 12...
