摘要
We discuss the spectra of multi-flavor massless QCD(2). An approximation in which the Hilbert space is truncated to two currents states is used. We write down a 't 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 't Hooft model and the large NS limit spectra are re-derived by using a description in terms of currents. (C) 2001 Elsevier Science B.V. All rights reserved.
