Type IIA brane configurations dual to IIB setups with D3s, D7s, and O7s on a transverse ${\mathbf{Z}}_2$ singularity. D4-branes wrap around the circle, dashed lines represent orientifold planes, and a cross represents NS5-branes. Cases (a) and (b) give rise to a theory on ${\mathrm{AdS}}_5\times {\mathbf{R}\mathbf{P}}^5$ without O7s. The dual field theory has $\mathcal{N}=4$ supersymmetry with $SO$ or $Sp$ gauge group, respectively. Cases (c) and (d) are dual to O7s in ${\mathrm{AdS}}_5\times S^5$. The field theory has $\mathcal{N}=2$ supersymmetry and Sp-SO gauge group with an antisymmetric or symmetric tensor hypermultiplet. Cases (e)–(h) represent O7s in ${\mathrm{AdS}}_5\times {\mathbf{R}\mathbf{P}}^5$. Cases (e) and (f) describe $Sp\times Sp$ and $SO\times SO$ gauge groups with bifundamental matter, and cases (g) and (h) describe a single $SU$ gauge group with two antisymmetric or symmetric tensor hypermultiplets. Case (g) is the theory described in detail in this work as it realizes the alternative baryon scenario. The setup (i) gives an $SO\times Sp$ product gauge group. Additional flavor branes can be added in all of the configurations.Reuse & Permissions
