symmetries. After integrating out all massive KK modes on $\Sigma_{\mathfrak{g}}$ we are left with an effective two-dimensional theory with $(0,2)$ supersymmetry. This is an old idea first explored in the current context in [@Bershadsky:1995vm; @Maldacena:2000mw] and subsequently generalized in many papers including [@Benini:2013cda; @Benini:2012cz; @Almuhairi:2011ws; @Naka:2002jz]. Based on these results it is natural to assume that the low-energy theory will be a $(0,2)$ SCFT. The consistency of the results below together with the holographic analysis in the subsequent sections provide strong evidence for the validity of this assumption.

The four Poincaré supercharges of $\mathcal{N}=4$ SYM are in the $(\bf{2}, \bf{4})$ representation of $SO(1,3)\times SO(6)$. After the relevant deformation in is turned on, only one of these supercharges is preserved and this is the supercharge present at the $\mathcal{N}=1$ LS fixed point.[^3] The supercharge has the same charges under $U(1)_R$ and $U(1)_F$ as the gaugino $\lambda$ in Table \[table:two\]. After putting the four-dimensional theory on $\mathbb{R}^{1,1}\times \Sigma_{\frak{g}}$, in order to implement the topological twist and preserve some supersymmetry, we turn on a background gauge field along the generator $$\label{Tback}
T_{\mathfrak{b}} =\frac{\kappa}{2}\, T_R^{\rm LS} +\mathfrak{b} \,T_F \;,$$ where $$\label{TF}
T_{F} = \frac{1}{2}(T_1-T_2)\;,$$ is the Cartan generator of the $SU(2)_F$ flavor symmetry. The
