The Quartic Effective Action for the Heterotic String
TL;DR: In this paper, the complete low-energy effective action to quartic order in the bosonic fields for the heterotic string was calculated and shown to reduce to the supergravity sector of the superstring when the gauge connection is equal to the generalized spin connection.

Eric Bergshoeff,M. de Roo +1 more
TL;DR: The supersymmetric quartic effective action for the heterotic string which follows from the supersymmetrization of the Yang-Mills and Lorentz Chern-Simons forms was presented in this paper.

Anomaly cancellations in supersymmetric D=10 gauge theory and superstring theory
TL;DR: In this article, a superstring theory for E 8 × 8 × E 8 has been constructed, based on SO(32) and the remaining pieces of all the anomalies cancel if the gauge group is SO (32) or E 8×E 8.

Strings in background fields
TL;DR: In this article, the propagation of strings in background fields, including the effects of metric, antisymmetric tensor, and dilaton expectation values, as well as gauge field backgrounds in the case of heterotic strings, is studied.

A Relation Between Tree Amplitudes of Closed and Open Strings
TL;DR: In this article, the authors derive a formula which expresses any closed string tree amplitude in terms of a sum of the products of appropriate open string tree amplitudes, which is applicable to the heterotic string as well as to the closed bosonic string and type II superstrings.
