Description
We present exact results in SU($N_C$) chiral gauge theories with charged fermions in an antisymmetric, $N_F$ fundamental, and $N_C + N_F − 4$ anti-fundamental representations. We achieve this by considering the supersymmetric version of these theories and utilizing anomaly mediated supersymmetry breaking at a scale $m ≪ Λ$ to generate a vacuum. The connection to non-supersymmetric theories is then argued by taking the limit $m → ∞$. For odd $N_C$, we determine the massless fermions and unbroken global symmetries in the infrared. For even $N_C$, we find global symmetries are non-anomalous and no massless fermions. In all cases, the symmetry breaking patterns differ from what the tumbling hypothesis would suggest.
