Résumé
A measurement of gamma-gamma production of the final states K+K-π+π-, K+K+π0π0, K0SK0Sπ+π -, K0S K±π∓π0 and K0S K0Sπ0π0 was performed by the ARGUS collaboration at the e+ e- storage ring DORIS II at DESY. Since the two intermediate states K*0 K̄*0 and K*+ K*- are accessible by analysing different final states, the measurement provides several cross checks for cross-sections to these two states. The results for γγ → K* K̄* cross-sections obtained from different final states are found to be consistent with each other. The analysis of the partial wave structure of the K*0 K̄*0 state from the reaction γγ → K+ K-π+π- revealed the dominance of the (JP, Jz) = (2+, ±2) wave.
