Description
We present a study of a chirally symmetric model of four fermion interactions, the Nambu Jona-Lasinio model, on the lattice with Wilson fermions. Four fermion interactions are a necessary part of many models of beyond Standard Model physics. In particular, they can couple the Standard Model fermions to a strongly interacting Higgs sector. In technicolor models they may cause spontaneous chiral symmetry breaking and modify the running coupling. As a first step, we study the restoration and spontaneous breaking of chiral symmetry in the lattice NJL model before adding a gauge interactions.
