Massless QCD2 from current constituents Original Research

We discuss the spectra of multi-flavor massless QCD2. An approximation in which the Hilbert space is truncated to two currents states is used. We write down a ʹt Hooft like equation for the wave function of the two currents states. We solve this equation for the lowest massive state and find an excellent agreement with the DLCQ results. In addition, the ʹt Hooft model and the large Nf limit spectra are re-derived by using a description in terms of currents.
