ηc(2980) production in γγ interactions has been detected via its decays into K 0 s K ± π ∓ , K + K -K + K -and K + K -π + π -in the data taken with the DELPHI detector at LEP1 and LEP2 energies. The two-photon radiative width averaged over all observed decay channels is Γγγ = 13.9 ± 2.0 (stat.) ± 1.
A search for the pseudoscalar meson η b is performed in two-photon interactions using the L3 detector at LEP. The data sample corresponds to a total integrated luminosity of 610 pb -1 collected at the centre-of-mass energies from 189 GeV to 209 GeV. Preliminary results of the analysis in the η b mas
