Dynamical chiral symmetry breaking with Minkowski space integral representations
Dynamical chiral symmetry breaking with Minkowski space integral representations
The fermion propagator is studied in the whole Minkowski space with the help of the Schwinger-Dyson equations. Various integral representations are employed to get solutions for the dynamical breaking of chiral symmetry in different regimes of the coupling constant. In particular, in the case of massive boson, we extend the …
