✦ Synopsis

We study deviations from the perturbative asymptotic behaviour in the running QCD coupling by analysing non-perturbative measurements of e,(p) at low momenta (p x 2 GeV) as obtained from the lattice three-gluon vertex. Our exploratory study provides some evidence for power corrections to the perturbative running proportional to l/p*.
