Open-closed superstring amplitudes using vertex operators in AdS5 × S5

Abstract

Abstract: Using the pure spinor formalism, a particular superstring scattering amplitude involving one closed string and N open string vertex operators in AdS5 × S5 is studied. It is shown that the tree-level amplitude containing one supergravity state and N super-Yang-Mills states located on D3-branes near the AdS5 boundary can be expressed as a d = 4 (Formula presented.) harmonic superspace integral in terms of the supergravity and super-Yang-Mills superfields.
