A Study of the Charge of Leading Hadrons in Gluon and Quark Fragmentation
Abstract
Description
In this study the electric charges of leading systems in quark and gluon jets from hadronic three-jet events in $e^+e^-$-annihilation measured with the DELPHI-experiment are examined. Leading systems are defined by a rapidity gap between the leading system of a jet and the rest of the event. The measured charge distributions are compared with results from Monte-Carlo simulations which do not contain colour-octet neutralisation processes. In the data an enhanced production of neutral leading systems compared to Monte-Carlo predictions is found in gluon jets, which is compatible with the expectations from colour-octet neutralisation. The quark jet sample is found in agreement with the simulation.
