Pulsating strings from two-dimensional CFT on (T4)N/S(N)(T4)N/S(N)

We propose a state from the two-dimensional conformal field theory on the orbifold (T4)N/S(N)(T4)N/S(N) as a dual description for a pulsating string moving in AdS3AdS3. We show that, up to first order in the deforming parameter, the energy in both descriptions has the same dependence on the mode number, but with a non-trivial function of the coupling.
