TL;DR

This paper systematically classifies asymmetric orbifold models derived from non-supersymmetric heterotic strings, exploring both standard and non-standard embeddings, and constructs examples of supersymmetric models within this framework.

Contribution

It provides a comprehensive classification of asymmetric orbifold models from non-supersymmetric heterotic strings and introduces new supersymmetric models based on these strings.

Findings

Classified asymmetric orbifold models with standard embeddings.

Identified geometrically interpretable toroidal compactifications.

Constructed supersymmetric models from non-supersymmetric heterotic strings.

Abstract

We investigate asymmetric orbifold models constructed from non-supersymmetric heterotic strings. We systematically classify the asymmetric orbifold models with standard embeddings and present a list of asymmetric orbifolds which are geometrically interpreted as toroidal compactifications of non-supersymmetric heterotic strings. By studying non-standard embedding models, we also construct examples of the {\em supersymmetric} asymmetric orbifold models based on non-supersymmetric heterotic strings.
