Model of U(1) chiral-symmetry breaking
Description
An SU(2) gauge-theory model of spontaneous chiral-symmetry breaking through the nonvanishing vacuum expectation value of spin-zero fields is examined. For the case of two fermion flavors, the model explicitly demonstrates the 't Hooft resolution of the U(1) problem through instanton effects. The absence of any conflict with the current-algebra relations of chiral perturbation theory point to a clearer understanding of the gauge-theory vacuum theta periodicity in the case of broken chiral symmetries
