COMPARISON OF CHARGED-PARTICLE MULTIPLICITIES IN QUARK AND GLUON JETS PRODUCED IN E+E- ANNIHILATION AT 29 GEV

Journal article

The charged particle multiplicities of the quark and gluon jets in the three-fold symmetric e+e- → qqg events at √s = 29 GeV have been studied using the high resolution spectrometer at PEP. A value of 〈n〉g = 6.7-2.1+1.1±1.0 for gluon jet s with an energy of 9.7-2.0+1.5 GeV is measured. The ratio, 〈n〉g/〈n〉q, is 1.29-0.41+0.21±0.20, which i s significantly lower than the value of 9 4 naively expected from the ration of the gluon-to-quark color charges. © 1985.
