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