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.

## 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

Using a synthesis of the functional integral and operator approaches we discuss the fermion-boson mapping and the role played by the Bose field algebra in the Hilbert space of two-dimensional gauge and anomalous gauge field theories with massive fermions.

Conformal invariance conditions on a sigma model of the open bosonic string including the tachyon, the abelian gauge field an the first excited massive mode are calculated up to order a'. Inner symmetries are used to compute conformal invariance conditions from renormalization group beta functions.
