TL;DR

This paper introduces a matrix model for type 0 strings using a non-supersymmetric orbifold projection, connecting various string theories and M-theory through different limits.

Contribution

It constructs a novel matrix model for type 0 strings, including both type A and B, and demonstrates its ability to interpolate between multiple string theories and M-theory.

Findings

Correct partition function derived

Spectrum of branes identified

Model interpolates between four string theories and M-theory

Abstract

A matrix model for type 0 strings is proposed. It consists in making a non-supersymmetric orbifold projection in the Yang-Mills theory and identifying the infrared configurations of the system at infinite coupling with strings. The correct partition function is calculated. Also, the usual spectrum of branes is found. Both type A and B models are constructed. The model in a torus contains all the degrees of freedom and interpolates between the four string theories (IIA, IIB, 0A, 0B) and the M theory as different limits are taken.
