We discuss twisted states of AdS orbifolds which couple to N = 2 chira
l primary operators not invariant under exchange of the gauge factors.
Kaluza-Klein reduction on the fixed circle gives the correct conforma
l dimensions of operators in the superconformal theory and involves so
me aspects of monopole dynamics in the non-trivial background. As a by
product we found evidence for decoupling of U(1) factors in the four-d
imensional gauge theory. (C) 1998 Elsevier Science B.V. All rights res
