The Massless Spectrum of Heterotic Compactifications

TL;DR

This paper analyzes the massless spectrum resulting from heterotic string compactifications to four dimensions, linking four-dimensional effective theory conditions with ten-dimensional moduli space computations.

Contribution

It provides a unified approach to compute the massless spectrum using F-term conditions and confirms consistency with ten-dimensional moduli space results.

Findings

Agreement between four-dimensional F-term analysis and ten-dimensional moduli computations

Explicit characterization of the massless spectrum in heterotic compactifications

Insights into anomaly cancellation conditions in the compactification process

Abstract

We discuss the four-dimensional massless spectrum of supersymmetric Minkowski compactifications of ten-dimensional heterotic supergravity, including the anomaly cancelation condition. This can be calculated from restrictions arising from F-term conditions in a four-dimensional effective theory. The results agree with computations of the infinitesimal moduli space recently performed from a ten-dimensional perspective. The paper is based on a talk given by Eirik Eik Svanes in Leuven for the workshop on "The String Theory Universe".
