Abstract.
A measurement of gamma–gamma production of the final states \(K^+ K^- \pi^+ \pi ^-\), \(K^+ K^- \pi^0 \pi ^0\), \(K^0_SK^0_S\pi^+\pi^-\), \(K^0_S K^{\pm} \pi^{\mp} \pi^0\) and \(K^0_SK^0_S\pi^0\pi^0\) was performed by the ARGUS collaboration at the \(e^+e^-\) storage ring DORIS II at DESY. Since the two intermediate states \(K^{*0} \bar{K}^{*0}\) 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 \(\gamma\gamma \to K^{*}\bar{K}^*\) cross-sections obtained from different final states are found to be consistent with each other. The analysis of the partial wave structure of the \(K^{*0}\bar{K}^{*0}\) state from the reaction \(\gamma \gamma \to K^+ K^- \pi^+ \pi ^-\) revealed the dominance of the \((J^P,J_z) = (2^+,\pm 2)\) wave.
