Abstract
We extend the proposal of Berenstein, Maldacena and Nastase to
the Type IIB
superstring propagating on a pp-wave over the
orbifold.
We show that first-quantized free string theory is described
correctly
by the large-
N, fixed gauge coupling limit of
[U(N)]k
quiver gauge theory. We propose a precise map between gauge theory
operators
and string states for both untwisted and twisted sectors. We
also compute
leading-order perturbative correction to the anomalous dimensions
of these
operators. The result is in agreement with the value deduced
from the
string
energy spectrum, thus substantiating our proposed operator-state
map.
