Abstract / Description:The pseudoscalar meson eta_b has been searched for in two-photon interactions at LEP II. The data sample corresponds to a total integrated luminosity of 617 pb^{-1} at centre-of-mass energies ranging from 161 to 209 GeV. Upper limits at a confidence level of 95% on the product Gamma_{\gamma\gamma}(eta_b) x BR(eta_b) are 190, 470 and 660 eV/c^2 for the eta_b decaying into 4, 6 and 8 charged particles, respectively.
