Description
The integrability program provides powerful tools to determine the spectrum of holographic theories. The development of these tools and the generalisation to a wider scope of theories go hand in hand. In particular, non-supersymmetric versions of AdS/CFT can be accessed, which is a first step towards more realistic models of QCD and could shed some light on SUSY-breaking mechanisms needed for phenomenology.
We discuss the simple case of orbifolds of $AdS_5\times S^5$ and the dual $\mathcal{N}=4$ super Yang-Mills theory. We explain how the orbifolding features in the various integrability techniques and demonstrate this for two simple $\mathbb{Z}_2$-orbifolds. When we break supersymmetry completely, we expect tachyons to appear on both sides of the duality and we comment on their implications and potential matching through AdS/CFT.
