Heterotic Matrix String Theory

TL;DR

This paper identifies and studies the states in matrix theory that correspond to fundamental heterotic strings, advancing the nonperturbative understanding of heterotic string theory via M-theory.

Contribution

It explicitly identifies heterotic string states within matrix theory and analyzes their interactions, providing new insights into heterotic M-theory formulations.

Findings

Heterotic string states are explicitly constructed in matrix theory.

Interactions of these states are analyzed within the matrix model.

Comments on analogous states in Type IIA string theory are provided.

Abstract

M-theory suggests the large N limit of the matrix description of a collection of N Type IA D-particles should provide a nonperturbative formulation of heterotic string theory. In this paper states in the matrix theory corresponding to fundamental heterotic strings are identified, and their interactions are studied. Comments are made about analogous states in Type IIA string theory, which correspond to bound states of D-particles and D-eightbranes.
