A model independent observation of the string effect using quark tagging at LEP
1991
Abstract
Quarkand
gluonin 3-jet events from hadronic Z 0 decays are identified through use of the semi-leptonic decays of charm and
bottom quarks. This tagging method allows geometrically symmetric or
transposedconfigurations of the
quarkand
gluonjets to be selected, permitting a study of the asymmetry in the population of particles in the regions between jets, commonly called the string effect, which avoids restrictions present in previous studies. In particular, our demonstration of a population asymmetry is performed without use of a model. Our results imply that dynamical differences exist between
quarksand
gluonsor between
quark-antiquark and
quark-
gluonjet systems with respect to their particle production properties.
