Measurement of the cross-section for the process $ee \to ee\gamma^{*}\gamma^{*} \to eeX$ at $\sqrt{S_{ee}}$ = 189 GeV
The hadronic structure of interactions of virtual photons ( gamma *) is investigated using the reaction ee to ee gamma * gamma * to eeX based on data taken by the OPAL experiment at square root (S/sub ee/) =189 GeV, where X represents the hadronic final state. The measured differential cross-section...
