Two-Dimensional Baryons in the Large-N Limit
/ Authors
/ Abstract
We propose a bilocal field theory for mesons in two dimensions obtained as a kind of non-local bosonization of two-dimensional QCD. Its semiclassical expansion is equivalent to the 1/Nc expansion of QCD. Using an ansatz we reduce the classical equation of motion of this theory in the baryon number one sector to a relativistic Hartree equation and solve it numerically. This (non-topological) soliton is identified with the baryon.
