# Spectrum of supersymmetric and bosonic open 2-branes

## TL;DR

This paper investigates the quantization and spectral properties of supersymmetric and bosonic open 2-branes, revealing a discrete spectrum for the supersymmetric case and no massless states for the bosonic case.

## Contribution

It provides a detailed analysis of the spectra of open 2-branes, highlighting differences between supersymmetric and bosonic models under flat metric conditions.

## Key findings

- Supersymmetric open 2-brane spectrum is discrete.
- Bosonic open 2-brane lacks massless states.
- Quantization under flat metric conditions was performed.

## Abstract

We consider both the supersymmetric open 2-brane and bosonic open 2-brane, their quantization and spectrum under the flat metric condition. The supersymmetric spectrum turns out to be discrete, while the spectrum of purely bosonic open 2-brane is shown to be devoid of any massless states.
