The Near-Flat-Space and BMN Limits for Strings in AdS4 x CP3 at One Loop

Understand

This paper studies type IIA string theory in AdS4 x CP3 in both the BMN limit and the Maldacena-Swanson or near-flat-space limit.

• We derive the simpler Lagrangian for the latter limit by taking a large worldsheet boost of the BMN theory.
• We then calculate one-loop corrections to the correlators of the various fields using both theories.
• In all cases the near-flat-space results agree with a limit of the BMN results, providing evidence for the quantum consistency of this truncation.
