摘要：

In an effort to obtain insights on the behavior of an interacting theory of fermions on the lattice that possesses the QCD chiral symmetry, the two flavor Nambu-Jona-Lasinio model with SU(2) x SU(2) chiral symmetry is studied on the four-dimensional hypercubic lattice using large N techniques and numerical simulations. Naive and Wilson fermions are considered and transparent results are obtained regarding the following: the approach to the zero quark and zero pion mass limits, the size of the 1/N corrections, the effects of the zero momentum fermionic modes on finite lattices, and the scalar and pseudoscalar spectrum. Some interesting observations are made by viewing the model as the low energy approximation to QCD, as well as an embedding theory of the Higgs sector.
