Strong Hadronic Decays in Qcd2.
Strong hadronic decays are discussed in the 't Hooft model for the two-dimensional QCD in the limit of infinite number of colours. Adler selfconsistency condition is derived for decays with pions in the final state and the corresponding amplitude is demonstrated to vanish identically in the chiral limit. The 't Hooft model for QCD in two dimensions in the limit of infinite number of colours 1 i...
متن کاملSpectrum of quarks in QCD2
The properties of the gauge invariant two-point quark Green's function are studied in the large-N c limit of two-dimensional QCD. The analysis is done by means of an exact integrodifferential equation. The Green's function is found to be infrared finite, with singularities in the momentum squared variable represented by an infinite number of threshold type branch points with a power-3/2, starti...
متن کاملThe Adjoint Vacuum Sector of Massless Qcd2
We consider a “one current” state, obtained by application of a color current on the “adjoint” vacuum, in QCD2, with quarks in fundamental representation. The quarks are taken to be massless. The theory on the light-front can be “currentized”, 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...
متن کاملMassless QCD2 From Current Constituents
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 ’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 Nf limit spe...
متن کاملMesonic Spectra of Bosonized QCD2 Models
We discuss bosonized two-dimensional QCD with massless fermions in the adjoint and multi-flavor fundamental representations. We evaluate the massive mesonic spectra of several models by using the lightfront quantization and diagonalizing the mass operator M2 = 2P+P−. We recover previous results in the case of one flavor adjoint fermions and we find the exact massive spectrum of multi flavor QCD...
