Pulsating strings on AdS5 x S5

We find the anomalous dimension and the conserved charges of an R-charged string pulsating on AdS5. The analysis is performed both on the gauge and string side, where we find agreement at the one-loop level. Furthermore, the solution is shown to be related by analytic continuation to a string which is pulsating on S5, thus providing an example of the close relationship between the respective isometry groups.
