Abstract

Arguably, the simplest chiral gauge theories are SO(10) with Nf fermion fields in the spinor representation 16. We study their dynamics using their supersymmetric limits perturbed by an infinitesimal anomaly mediated supersymmetry breaking as a guide. We predict the theory is gapped for Nf=1, 2, while the SU(Nf) global symmetry is broken to SO(Nf) for moderately large Nf≥3.
