Abstract
The mass of the gluon is determined using asymptotic perturbative QCD in the renormalization scheme. The experimental determination of the couplant ās(2), which occurs in the perturbation expansions for and together with an estimate of the on-shell couplant, αs=0.096±0.016 [or αs(0)=0.30±0.05], yields the results if typical current (constituent) masses are assigned to the quarks.Keywords
