A New Type of String Field Theory

TL;DR

This paper introduces a novel approach to second quantization in string theory by representing strings through separate right and left mover modes, resulting in a free string field theory.

Contribution

It presents a new second quantization method based on separate Fock spaces for right and left mover modes, leading to a free string field theory.

Findings

The theory is formulated as a free theory with separate Fock spaces.

The approach simplifies string interactions by focusing on constituent modes.

It provides a new framework for string second quantization.

Abstract

We propose a new way of second quantizing string theory. The method is based on considering the Fock space of strings described by constituents which make up the $X^\mu_R$ and the $X^\mu_L$ i.e. the right and left mover modes separately. A state with any number of strings get represented by the Cartesian product of two free particle Fock spaces, one for right mover degrees of freedom, and one for left. The resulting string field theory is a free theory.
