String coupling constant seems to be 1

TL;DR

The paper argues that the string coupling constant should be 1, based on matching area spectra from loop quantum gravity and stringy differential geometry, suggesting a fundamental link between these theories.

Contribution

It introduces a reasoning framework connecting loop quantum gravity and stringy differential geometry to determine the string coupling constant value.

Findings

String coupling constant is argued to be 1.

Matching area spectra from two theories supports this value.

Provides a novel link between loop quantum gravity and string theory.

Abstract

We present a reasoning that the string coupling constant should be 1 from the assumption that the area spectrum derived from loop quantum gravity must be equal to the area spectrum calculated from "stringy differential geometry." To this end, we will use the loop quantum gravity area spectrum constructions proposed by Brian Kong and us, and stringy differential geometry based on double field theory recently proposed by Imtak Jeon, Kanghoon Lee and Jeong-Hyuck Park.
