alpha'-Corrections to Heterotic Superstring Effective Action Revisited

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 \(\alpha'\) equivalent modulo field redefinitions to heterotic string effective actions computed by different me...

Description
Summary: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 \(\alpha'\) equivalent modulo field redefinitions to heterotic string effective actions computed by different methods.
