We recall also that an explicit one-loop heterotic string calculation demonstrated that the Chamseddine-Chapline-Manton action is unrenormalized, whereas terms of higher order in the gauge fields are generated: J. R. Ellis, P. Jetzer and L. Mizrachi, Nucl. Phys. B 303

In the presence of fermions, such redefinitions would yield higher-derivative corrections in the fermionic sector of the effective Lagrangian, such as terms of the form c M P 2 ∫ d 4 x ψ ¯ γ μ ∇ ν F μ ν ψ \frac{c}{M_{P}^{2}}\int d^{4}x\overline{\psi}\gamma^{\mu}\nabla^{\nu}F_{\mu\nu}\psi
