Description
The KS0K±π± and ηπ+π- final states in two-photon collisions are studied with the L3 detector at LEP using data collected at centre of mass energies from 183 to 202 GeV. The mass spectrum of the KS0K±π± final state shows an enhancement around 1470 MeV, which is identified with the pseudoscalar η(1440). This state is observed in the γγ collisions for the first time and the value of its two-photon width is obtained. In the ηπ+π- channel only the f1(1285) is observed, upper limits for the formation of η(1440) and η(1295) are given. (author)
