N2 - We consider a "one-current" state obtained by application of a colour current on the "adjoint" vacuum in QCD 2 with quarks in the fundamental representation. The quarks are taken to be massless. The theory on the light-front can be "currentised" namely formulated in terms of currents only. The adjoint vacuum is obtained by applying a current derivative at zero momentum on the singlet vacuum. In general, the "one-current" states are not eigenstates of M 2 = 2 P + P -, except in the large N f limit. Problems with infrared regularisations are pointed out. Connection to fermionic structure is made. This talk is based on the paper of Ref. [A. Abrashkin, Y. Frishman and J. Sonnenschein, Nucl. Phys. B 703 (2004) 320, arXiv:hep-th/0405165] by the same authors.
