It introduces a detailed procedure for deriving string field theory from gauge theory in the large N limit, including the effects of interactions.

Findings

Demonstrates the string field theory interaction with operator insertion at the interaction point.

Analyzes the effects of Yang-Mills interactions on general BMN states.

Provides a framework for connecting gauge theory and string field theory in the pp wave background.

Abstract

We continue the development of a systematic procedure for deriving closed string pp wave string field theory from the large N Berenstein-Maldacena-Nastase limit. In the present paper the effects of the Yang-Mills interaction are considered in detail for general BMN states. The SFT interaction with the appropriate operator insertion at the interaction point is demonstrated.
