A PSU(2, 2|4)-invariant A-model constructed from fermionic superfields has recently been proposed as a sigma model for the superstring on AdS5 × S. After explaining the relation of this A-model with the pure spinor formalism, the A-model action is expressed as a gauged linear sigma model. In the zero radius limit, the Coulomb branch of this sigma model is interpreted as D-brane holes which are related to gauge-invariant N = 4 d=4 super-Yang-Mills operators. As in the worldsheet derivation of… CONTINUE READING
