String Models with Massive boson-fermion Degeneracy

TL;DR

This paper explores string models exhibiting a unique Massive boson-fermion Degeneracy Symmetry (MSDS), proposing these vacua as potential descriptions of the universe's early non-geometrical phase.

Contribution

It introduces a new class of string vacua with MSDS, offering a novel approach to modeling the universe's initial non-geometrical state.

Findings

Constructed string vacua with MSDS symmetry.

Proposed MSDS vacua as models for early universe.

Discussed implications for cosmology and string theory.

Abstract

We discuss constructions of string vacua with a novel Massive boson-fermion Degeneracy Symmetry (MSDS) as candidate vacua able to describe the early non-geometrical era of the universe. Based on a talk given at the Workshop on Cosmology & Strings, Corfu Institute, Greece, Sept 12, 2009.
