Marginally deformed AdS5/CFT4 and spindle-like orbifolds

Abstract

Abstract We study marginal deformations of $$ \mathcal{N} $$ N = 2, d = 4 long linear quiver CFTs using the holographic description. We find a two-parameter family of AdS5 solutions that generically break all of supersymmetry, but preserve $$ \mathcal{N} $$ N = 1 for a particular tuning of the parameters. We study the G-structure of the $$ \mathcal{N} $$ N = 2 “parent” and the $$ \mathcal{N} $$ N = 1 backgrounds and carefully discuss the quantisation of charges in all cases. For the $$ \mathcal{N} $$ N = 1 and $$ \mathcal{N} $$ 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.
