Abstract

Two-photon production of the hadronic final states K+K-π+π- and K+K-π+π0π- has been studied using the ARGUS detector at the e+e- storage ring DORIS II at DESY. The cross sections of the reactions γγ → øρ{variant}0 and γγ → øω have been measured for the first time. In addition, angular distrubutions have been determined for the reaction γγ → øρ{variant}0 → K+K-π+π-.
