Contribution

It explicitly demonstrates a massive boson-fermion degeneracy symmetry (MSDS) in string theories, distinct from traditional supersymmetry, with potential applications in cosmology and particle physics.

Findings

Discovery of Massive Spectrum Degeneracy Symmetry (MSDS) in string models.

MSDS distinguishes from conventional supersymmetry.

Proposals for MSDS applications in early universe and black hole theories.

Abstract

The existence of a new kind of massive boson-fermion symmetry is shown explicitly in the framework of the heterotic, type II and type II orientifold superstring theories. The target space-time is two-dimensional. Higher dimensional models are defined via large marginal deformations of JxJ-type. The spectrum of the initial undeformed two dimensional vacuum consists of massless boson degrees of freedom, while all massive boson and fermion degrees of freedom exhibit a new Massive Spectrum Degeneracy Symmetry (MSDS). This precise property, distinguishes the MSDS theories from the well known supersymmetric SUSY-theories. Some proposals are stated in the framework of these theories concerning the structure of: (i) The Early Non-singular Phase of the Universe, (ii) The two dimensional boundary theory of AdS3 Black-Holes, (iii) Plausible applications of the MSDS theories in particle physics, alternative to SUSY.
