TL;DR

This paper constructs a new N=1 supersymmetric heterotic string model on asymmetric orbifolds, revealing supercurrents arising solely from twisted sectors, which advances understanding of string compactifications.

Contribution

It introduces a novel N=1 supersymmetric model on asymmetric orbifolds with supercurrents originating only from twisted sectors, expanding the landscape of string theory models.

Findings

Supercurrents appear only from twisted sectors.

The model is N=1 space-time supersymmetric.

Uses asymmetric orbifolds associated with Lie algebras.

Abstract

We study $E_8 \times E_8$-heterotic string on asymmetric orbifolds associated with semi-simple simply-laced Lie algebras. Using the fact that $E_6$-model allows different twists, we present a new N=1 space-time supersymmetric model whose supercurrent appears from twisted sectors but not untwisted sector.
