chosen so that the discrete chiral symmetry formula_5 of the original model is enhanced to a continuous U(1)-valued chiral symmetry formula_6. Chiral symmetry breaking occurs as before, caused by the same VEV. However, as the spontaneously broken symmetry is now continuous, a massless Goldstone boson appears in the spectrum. Although this leads to no problems at the leading order in the 1/N expansion, massless particles in 2-dimensional quantum field theories inevitably lead to infrared divergences and so the theory appears to not exist.
