Abstract
A measurement of gamma-gamma production of the final states K(+)K(-)pi(+)pi (-), K(+)K(-)pi(0)pi(0), K(S)(0)K(S)(0)pi(+)pi(-), K(S)(0)K(+/-)pi(-/+)pi(0 ) and K(S)(0)K(S)(0)pi(0)pi(0) was performed by the ARGUS collaboration at the e(+)e(-) storage ring DORIS II at DESY. Since the two intermediate stat es K*(0)(K) over bar*(0) and K*K+*(-) are accessible by analysing different final states, the measurement provides several cross checks for cross-sect ions to these two states. The results for gamma gamma --> K*(K) over bar* c ross-sections obtained from different final states are found to be consiste nt with each other. The analysis of the partial wave structure of the K*(0) (K) over bar*(0) state from the reaction gamma gamma --> K(+)K(-)pi(+)pi(-) revealed the dominance of the (J(P), J(z)) = (2', +/-2) wave.
