High Energy Physics - Theory 2008-11-26 v1

Abstract

In this letter we establish that the supersymmetric R^2 effective action for the heterotic string, obtained from the supersymmetrisation of the Lorentz Chern-Simons term, is to order α\alpha' equivalent modulo field redefinitions to heterotic string effective actions computed by different methods.
