Three-point correlators from string amplitudes: Mixing and Regge spins

Understand

This paper has two parts.

• We first compute the leading contribution to the strong-coupling mixing between the Konishi operator and a double-trace operator composed of chiral primaries by using flat-space vertex operators for the string-duals of the operators.
• We then compute the three-point functions for protected or unprotected scalar operators with higher spin operators on the leading Regge trajectory.
• Here we see that the nontrivial spatial structures required by conformal invariance arise naturally from the form of the polarization tensors in the vertex operators.
