Abstract: (Elsevier)

We calculate the complete low-energy effective action to quartic order in the bosonic fields for the heterotic string. We find that, in addition to the term involving Ξ(3) found previously, there are terms of the form Tr( F 2 − R 2 ) 2 and four- and six-derivative terms. We also show that the heterotic effective action reduces to that of the N = 1 supergravity sector of the superstring when the gauge connection is equal to the generalized spin connection.
