TL;DR

This paper applies a novel gauge theory quantization method to the Nambu-Goto action in four dimensions, achieving results that match the observed spectrum of light-quark mesons without gauge fixing.

Contribution

It introduces a new quantization approach for the Nambu-Goto action that preserves constraints and demonstrates its effectiveness in four dimensions.

Findings

The quantization method yields spectra consistent with light-quark mesons.

No gauge fixing is required in this formalism.

The approach shows promising agreement with experimental data.

Abstract

Recently, a new quantization method for gauge theories was proposed, in which no gauge fixing is required but the constraints are kept. Here we successfully applied this formalism to Nambu-Goto action in any dimensions. The result of our theoretical calculation have shown striking agreement with the spectrum of the light-quark mesons.
