Optimized-Variational Quark Mass Expansion and Dynamical Chiral Symmetry Breakdown

  • Jean-Löıc Kneur
  • Published 1996


A recently proposed variational mass expansion approach to dynamical chiral symmetry breakdown is reviewed. We briefly explain how a specific integral ansatz over the analytically continued, arbitrary Lagrangian mass parameter, resums the usual variational mass expansion (“delta-expansion”.) The construction is then generalized to obtain non-perturbative… (More)
