Some exact results in chiral gauge theories

We analyze dynamics of chiral gauge theories based on the $SU(N)$ group with one anti-symmetric tensor $A$ and $(N-4)$ anti-fundamentals $F_{i}$ when $N$ is odd. Based continuity to supersymmetric anomaly-mediated supersymmetry breaking, we claim that global $SU(N-4)$ symmetry spontaneously broken $Sp(N-5)$. There are $N-5$ massless fermions as a fundamental representation $Sp(N-5)$, another fermion, together saturating anomaly matching conditions. When even, unbroken flavor $Sp(N-4)$ while there no fermions. Our result different from suggested by tumbling where full unbroken, but picture can be modified via addition second condensate produce breaking pattern predicted our method.
