Query: Analysis of Spontaneous Mass Generation by Iterative Method in the
  Nambu-Jona-Lasinio Model and Gauge Theories   We propose a new iterative method to directly calculate the spontaneous mass
generation due to the dynamical chiral symmetry breaking. We can conclude the
physical mass definitely without recourse to any other consideration like the
free energy comparison.
