Chiral Symmetry Restoration and Parity Mixing
We derive the expressions of the vector and axial current from a chiral Lagrangian restricted to nucleons and pions. They display mixing terms between the axial and vector currents. We study how the modification of the quark condensate affects the coupling constants of the axial cur- rent, namely th...
