Comment on the Background Independent Open String Theory

TL;DR

This paper provides a direct derivation of the string field theory action within Witten's background independent open string theory framework, focusing on the case where ghosts and matter are decoupled, and discusses its implications.

Contribution

It offers a novel direct derivation of the string field theory action in a specific background independent open string theory setting.

Findings

Derived the string field theory action explicitly

Analyzed consequences of the derived action

Focused on decoupled ghosts and matter case

Abstract

A direct derivation of the string field theory action in the Witten's background independent open string theory for the case when ghosts and matter are decoupled is given and consequences are discussed.
