Variational Quark Mass Expansion and the Order Parameters of Chiral Symmetry Breaking
We investigate in some details a ``variational mass" expansion approach, generalized from a similar construction developed in the Gross-Neveu (GN) model, to evaluate the basic order parameters of the dynamical breaking of the $SU(2)_L \times SU(2)_R$ and $SU(3)_L \times SU(3)_R$ chiral symmetri...
