“…In the case of holographic supersymmetric fixed points, much of the insight into their dynamics is obtained through their dual AdS 6 geometries [5,53,54]. Recently, non-SUSY AdS 6 solutions of type II supergravities have appeared in [55,56].…”

We consider generalisations of the recently proposed supersymmetry breaking deformation of the 5d rank-1 E_1E1 superconformal field theory to higher rank. We generalise the arguments to theories which admit a mass deformation leading to gauge theories coupled to matter hypermultiplets at low energies. These theories have a richer space of non-supersymmetric deformations, due to the existence of a larger global symmetry. We show that there is a one-to-one correspondence between the non-SUSY deformations of the gauge theory and their (p,q)(p,q) 5-brane web. We comment on the (in)stability of these deformations both from the gauge theory and the 5-brane web point of view. UV duality plays a key role in our analysis, fixing the effective Chern-Simons level for the background vector multiplets, together with their complete prepotential. We partially classify super-Yang-Mills theories known to enjoy UV dualities which show a phase transition where different phases are separated by a jump of Chern-Simons levels of both a perturbative and an instantonic global symmetry. When this transition can be reached by turning on a non-supersymmetric deformation of the UV superconformal field theory, it can be a good candidate to host a 5d non-supersymmetric CFT. We also discuss consistency of the proposed phase diagram with the ’t Hooft anomalies of the models that we analyse.

“…Quantities which are monotonic along RG flows provide viable counting functions and have been established in various dimensions [17][18][19][20][21][22][23][24]. In 5d, the existence of a counting function remains conjectural, with supporting evidence in [25][26][27][28][29]. Whether RG monotones exist for the de-…”

We use a combination of AdS/CFT and supersymmetric localization to study codimension-2 defects in 5d SCFTs and their gauge theory deformations. The 5d SCFTs are engineered by (p, q) 5-brane webs, with defects realized by D3-branes ending on the 5-brane webs. We obtain the defect free energies and find that gauge theory descriptions of the combined 5d/3d systems can be connected to the UV defect SCFTs through a form of F-maximization which extremizes over different gauge theory defects. This leads to a match between the defect free energies obtained from supersymmetric localization in the gauge theories on the one hand and string theory results on the other. We extend this match to defect RG flows.

We enlarge the dictionary between matrix models for long linear quivers preserving eight supercharges in d=5d=5 and d=3d=3 and type IIB supergravity backgrounds with AdS_{d+1}d+1 factors. We introduce mass deformations of the field theory that break the quiver into a collection of interacting linear quivers, which are decoupled at the end of the RG flow. We find and solve a Laplace problem in supergravity which realises these deformations holographically. The free energy and expectation values of antisymmetric Wilson loops are calculated on both sides of the proposed duality, finding agreement. With our matching procedure, the free energy satisfies a strong version of the F-theorem.
