Can we see the triple-gluon vertex already at 44 GeV?

A clear experimental test of the triple-gluon vertex is still lacking; however, it is a basic necessity for QCD to be asymptotically free. We discuss in this paper methods using jet flavor tagging, ordinary flavor tagging of a definite quark jet, or discrimination between the quark and gluon jets based on the different fragmentation properties of them, capable of testing the triple-gluon vertex in electron-positron annihilation at 44 GeV. An enriched sample of gluon jets, jets with the smallest energy in four-jet events, as well as a continuous tagging variable are also studied. Despite the fact that we have small statistics and the jets are not very well separated at this energy the differences between the observables defined in this paper are large enough to strictly distinguish between the Abelian model and QCD already at 44 GeV.
