More exact results on chiral gauge theories: The case of the symmetric tensor
Csaba Csáki, Hitoshi Murayama, Ofri Telem
Abstract
We study dynamics of $SU(N\ensuremath{-}4)$ gauge theories with fermions in rank-2 symmetric tensor and $N$ antifundamental representations, by perturbing supersymmetric theories with anomaly-mediated supersymmetry breaking. We find the $SU(N)\ifmmode\times\else\texttimes\fi{}U(1)$ global symmetry is dynamically broken to $SO(N)$ for $N\ensuremath{\ge}17$, a different result from conjectures in the literature. For $N<17$, the theory initially flows to a superconformal fixed point, but is diverted by the soft masses, which act as a relevant perturbation.
