Revisiting extremal couplings in AdS/CFT

Abstract We consider an effective theory of massive scalar fields on a fixed AdS d+1 background with a cubic extremal interaction among them. A bulk coupling is called extremal whenever the corresponding conformal dimension of any of the dual CFT d operators matches the sum of all the others. For cu...
