The student will use harmonic superspace to describe scattering amplitudes of superfields in the AdS_5 x S^5 background. With the pure spinor formalism of superstring theory, the vertex operators for these superfields were constructed using harmonic superspace in previous papers. The student will study how to relate these superstring vertex operators with superspace expressions of scattering amplitudes in the AdS_5 x S^5 background.
