Orbifolds of AdS5 × S5 and 4d conformal field theories Original Research Article

We study the relation between the large N limit of four-dimensional N= 2, 1, 0 conformal field theories and supergravity on orbifolds of AdS5 × S5. We analyze the Kaluza-Klein states of the supergravity theory and relate them to the spectrum of (chiral) primary operators of the (super) conformal field theories.
