The running strong coupling α(Q)s and the gluon propagator from QCD have been compared to similar quantities in the quanton model, a generalisation of QED with massless fermions (quantons) and scalar coupling of boson fields. In the latter model a series of bound states (which can be related to different flavours) have been obtained. Assuming a weighting of their momentum distributions with the average momentum Qi of each state, a running of the coupling α(Q) is obtained, which is in quantitative agreement with αs(Q) from QCD. Also with a similar weighting the gluon propagator from lattice QCD simulations is well described. This indicates clearly that QCD and thus the Standard Model is not a unique description of fundamental interactions. Different from the Standard Model, the quanton model is simple and yields bound states with correct masses. This may indicate that this model yields a more realistic description of fundamental forces.
