The 3-string vertex and the AdS/CFT duality in the PP-wave limit

TL;DR

This paper extends the string interaction vertex in the PP-wave background to a fully supersymmetric form and demonstrates agreement between string amplitudes and field theory results at leading order.

Contribution

It develops a complete supersymmetric 3-string vertex in the PP-wave background and compares string amplitudes with dual field theory calculations.

Findings

Successful extension of the 3-string vertex to full supersymmetry.

Agreement of string and field theory amplitudes at leading order.

Validation of the PP-wave limit in the AdS/CFT correspondence.

Abstract

We pursue the study of string interactions in the PP-wave background and show that the proposal of hep-th/0211188 can be extended to a full supersymmetric vertex. Then we compute some string amplitudes in both the bosonic and fermionic sector, finding agreement with the field theory results at leading order in lambda'.
