Description
We present results from simulations of a spin(4) lattice gauge theory in four
dimensions containing a single flavor of massless reduced staggered fermion. This model does not
allow for single site gauge invariant bilinear fermion terms and instead
we show that it develops a four fermion condensate in the confining regime. The absence of symmetry breaking is consistent with the cancellation of a 't Hooft anomaly corresponding to a discrete $Z_4$ symmetry.
If the spin(4) symmetry is extended to SU(4) we argue that in the naive continuum limit the model contains the matter representations and global symmetries
of the Pati-Salam GUT model in which we can embed a single family of the Standard
Model
