Dynamical truncation of the string spectrum at finite N

TL;DR

This paper introduces a nonperturbative, background-independent method to dynamically truncate the string spectrum and quantize the string coupling constant, derived from the Hamiltonian of Yang-Mills theory-based string dynamics.

Contribution

It presents a novel approach to string spectrum truncation and coupling quantization directly from Yang-Mills theory Hamiltonians, advancing nonperturbative string theory methods.

Findings

Nonperturbative truncation of string spectrum achieved.

String coupling constant quantized from Hamiltonian dynamics.

Background independence demonstrated in the truncation process.

Abstract

We exhibit a nonperturbative background independent dynamical truncation of the string spectrum and a quantization of the string coupling constant directly from the Hamiltonian governing the dynamics of strings constructed from Yang-Mills theories.
