| Abstract | The final state structure has been studied in single tagged gamma-gamma -> hadrons and compared to various models. The final state particles are found to lie at higher pseudorapidity relative to the tag than predicted by the models. This confirms the discrepancies recently observed by OPAL. Similar deviations are observed in the jet structure using a cone-based jet algorithm. A modified version of HERWIG is found to produce a better description of the data. |
