Confinement, i.e. the fact that bound states in QCD are colour singlets (or in other words: there are no free quarks or gluons) is experimentally well-established. There is no doubt that it is not just a prediction of lattice simulations, but a feature of strongly interacting systems at low energies, as no free quarks (or gluons) have yet been found within ...
