This event is part of the HET Seminar Series.

I discuss a model of reduced staggered fermions interacting through an SO (4) invariant four fermion interaction. I present theoretical arguments and numerical evidence which support the idea that the system develops a mass gap for sufficiently strong four fermi coupling without producing a symmetry breaking fermion bilinear condensate. Massless and massive phases appear to be separated by a continuous phase transition.
