Marginally deformed AdS5/CFT4 and spindle-like orbifolds

A bstract We study marginal deformations of N N = 2, d = 4 long linear quiver CFTs using the holographic description. We find a two-parameter family of AdS 5 solutions that generically break all of supersymmetry, but preserve N N = 1 for a particular tuning of the parameters. We study the G-structure of the N N = 2 “parent” and the N N = 1 backgrounds and carefully discuss the quantisation of charges in all cases. For the N N = 1 and N N = 0 cases, a picture emerges with “branes” back-reacted on either a spindle or its higher dimensional analogue. Comments on the marginally deformed dual CFTs are given, together with the study of some observables.
