The Emergence of Supersymmetry in $γ_i$-deformed ${\cal N}=4$ super-Yang-Mills theory

The $γ_i$-deformed $\mathcal{N}=4$ super-Yang-Mills theory is a non-supersymmetric deformation of the maximally-supersymmetric gauge theory in four dimensions which is conformally-invariant at the planar level. At the non-planar level non-trivial renormalization of marginal double-trace operators appears to break conformal invariance. At non-planar level, however, the behavior of this theory is less well understood. We study the one loop renormalization of the theory and the resulting flow of Yukawa and scalar coupling at the order ${\cal O}(\fracλ{N^2})$, and find $γ_i$ parameters receive nontrivial quantum corrections. We show that, at low energies, the $γ_i$ parameters flow to a common value and $γ_i$-deformed theory reaches an $\mathcal{N}=1$-supersymmetric fixed point described by the $β$-deformed $\mathcal{N}=4$ super Yang-Mills theory.
