The chiral limit of a fermion-scalar $(1/2{)}^{+}$ system in covariant gauges

A. Noronha, W. de Paula, J. H. de Alvarenga Nogueira +3

The homogeneous Bethe-Salpeter equation (BSE) of a (1/2)${}^{+}$ bound system, that has both fermionic and bosonic degrees of freedom, that we call a {\em mock nucleon}, is studied in…
