$QCD_{2}$ with massless quarks in terms of currents

We discuss the spectra of multi-flavor massless QCD/sub 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 f...

Sumario:We discuss the spectra of multi-flavor massless QCD/sub 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. The issue of the non-Hermiticity of the truncated Hamiltonian is also discussed. Talk based mainly on Nucl. Phys. B 596, 459 (2001).
