N2 - This talk reports on work aimed at improving our understanding of charged
states in gauge theories.Emphasis is placed on different ways of
implementingthe gauge invariance of physical states. QED perturbative
calculations are used to stress that gauge invariance is not enough: only a
subset of such states have a direct physical significance. In QCD a
non-perturbative obstruction means that quarks and gluons cannot form physical
states and as such these particles are not truely observables. This sets a
fundamental limit on the constituent quark model.
