Abstract: (Elsevier)

We study the low-energy physics of quarks in two dimensions, which are minimally coupled to CP n −1 fields. Within the 1 n expansion, heavy quarks are confined, the U(1) A chiral symmetry is spontaneously broken and a light isoscalar pseudoscalar boson is avoided via the axial anomaly.
