Study of Rapidity Gap Events in Hadronic Z Decays with the L3 Detector

A search is performed in symmetric 3-jet hadronic Z decay events for evidence of colour singlet exchange and for colour reconnection effects predicted by the Rathsman model. Asymmetries in particle flow and the angular separation of particles are found to be sensitive to such effects. 95% upper limi...

description A search is performed in symmetric 3-jet hadronic Z decay events for evidence of colour singlet exchange and for colour reconnection effects predicted by the Rathsman model. Asymmetries in particle flow and the angular separation of particles are found to be sensitive to such effects. 95% upper limits of 7-9% are found for the fraction of colour singlet exchange, and of 0.93% for the colour reconnection parameter $R_0$ (default value 0.1) of the Rathsman model.
