Abstract
We investigate the occurrence of power terms Lambda(2)/p(2) in the running QCD coupling by analysing non-perturbative measurements of alpha(s)(p) at q uite low momenta obtained from the lattice three-gluon vertex. Our study pr ovides some evidence for such a contribution. The phenomenological implicat ions of such a presence are reviewed.
