Twist Field as Three String Interaction Vertex in Light Cone String Field Theory

TL;DR

This paper explores the connection between the twist field in matrix string theory and the three-string interaction vertex in light-cone string field theory, showing that the vertex reproduces key operator product expansions.

Contribution

It demonstrates that the three-string interaction vertex can replicate important OPEs of the twist field, linking matrix string theory with light-cone string field theory.

Findings

The three-string vertex reproduces key OPEs of the twist field.

A close relation between matrix string theory and light-cone string field theory is established.

The study clarifies the role of the twist field as a three-string interaction vertex.

Abstract

It has been suggested that matrix string theory and light-cone string field theory are closely related. In this paper, we investigate the relation between the twist field, which represents string interactions in matrix string theory, and the three-string interaction vertex in light-cone string field theory carefully. We find that the three-string interaction vertex can reproduce some of the most important OPEs satisfied by the twist field.
