## Abstract

We consider a "one current" state, which is obtained by the application of a color current on the "adjoint" vacuum. This is done in QCD_{2}, with the underlying quarks in the fundamental representation. The quarks are taken to be massless, in which case the theory on the light-front can be "currentized", namely, formulated in terms of currents only. The adjoint vacuum is shown to be the application of a current derivative, at zero momentum, on the singlet vacuum. We apply the operator M^{2}=2P^{+} P^{-} on these states and find that in general they are not eigenstates of M^{2} apart from the large N_{f} limit. Problems with infra-red regularizations are pointed out. We discuss the fermionic structure of these states.
