Upon examining the effective action of the heterotic string theory at order *\alpha'^2*, an inconsistency between the Chern-Simons coupling *\Omega^2* and T-duality has been discovered. To address this issue, we introduce 60 parity-even independent geometrical couplings involving the *B*-field, metric, and dilation at the same order, each with arbitrary coefficients.... Show more
