In this thesis, a particular superstring scattering amplitude involving one closed string and N open string vertex operators in AdS5 ×S5 is studied in detail, usingthe pure-spinor formalism. After reviewing some background material and performing a few preliminary calculations, we show that the tree-level amplitude containing one supergravity state and N super-Yang-Mills states located on a D3-brane near the AdS5 boundary can be expressed as an N = 4, d = 4 harmonic superspace integral in terms of the supergravity and super-Yang-Mills superfields, thus proving a conjecture recently made
