Lattice Four-Fermion Interactions for Beyond Standard Model Physics
Abstract: We present a study of a lattice model of chirally symmetric four-fermion interactions, the Nambu Jona-Lasinio model, with Wilson fermions. Four fermion operators are a necessary part of many models of beyond Standard Model physics. In particular we are interested in technicolor models, where effective four-fermion operators are used to generate the standard model fermion masses. In the ideal walking scenario, the same interaction is responsible for breaking the chiral symmetry in an otherwise conformal model. As a first step, we study the restoration and spontaneous breaking of chiral symmetry in the lattice NJL model before adding a gauge interaction. We map the phase structure of the model and establish chiral symmetry breaking.
