Abstract

We consider the anomalous dimensions of restricted Schur polynomials constructed using n∼O(N) complex adjoint scalars Z and m complex adjoint scalars Y. We fix mn so that our operators are almost half Bogomol'nyi-Prasad-Sommerfield. At leading order in mn this system corresponds to a dilute gas of m free magnons. Adding the first correction of order mn to the anomalous dimension, which arises at two loops, we find nonzero magnon interactions. The form of this new operator mixing is studied in detail for a system of two giant gravitons with four strings attached.
