# Exotic baryons in two-dimensional QCD and the generalized sine-Gordon solitons

@article{Blas2007ExoticBI, title={Exotic baryons in two-dimensional QCD and the generalized sine-Gordon solitons}, author={H. Blas}, journal={Journal of High Energy Physics}, year={2007}, volume={2007}, pages={055-055} }

The solitons and kinks of the SU(3) generalized sine-Gordon model (GSG) are shown to describe the baryonic spectrum of two-dimensional quantum chromodynamics (QCD2). The GSG model arises in the low-energy effective action of bosonized QCD2 with unequal quark mass parameters. The GSG potential for Nf = 3 flavors resembles the potential of the effective chiral lagrangian proposed by Witten to describe low-energy behavior of four dimensional QCD. Among the attractive features of the GSG model are…
