On a CFT limit of planar ${\gamma }_i$-deformed $\mathcal{N}=4$ SYM theory

Christoph Sieg, Matthias Wilhelm

We show that an integrable four-dimensional non-unitary field theory that was recently proposed as a certain limit of the ${\gamma }_i$-deformed $\mathcal{N}=4$ SYM theory is incomplete an…
