More About the Multiplicity of Symmetric Three Jet Events / Hamacher, K ; Klapp, O ; Langefeld, P ; Siebel, M /DELPHI Collaboration
The measurement of the hadron multiplicity in mirror symmetric threejet events is compared to recent theoretical calculations.Jets are defined with the Cambridge algorithm.From this data in comparison to the hadronic multiplicity in \epem--annihilation a determination of the gluon to quarkcolour factor ratio yields:\begin{equation*}\frac{C_A}{C_F}= 2.221 \pm 0.032(\mathrm{stat}) \pm 0.047(\mathrm{exp})\pm 0.058(\mathrm{hadc}) \pm 0.075(\mathrm{theo}) \quad .\end{equation*}A measurement of the hadron multiplicity in equivalent gluon gluon events asfunction of the energy scale is presented.The increase with energy scale of the hadron multiplicity in gluongluon events is observed to be about twice as strong as inquark antiquark events. This presents very direct evidence for thetriple gluon vertex and the higher colour charge of the gluon..
