Effective action of heterotic string theory at order α′2
Abstract Upon examining the effective action of the heterotic string theory at order α′2, an inconsistency between the Chern-Simons coupling Ω2 and T-duality has been discovered. To address this issue, we introduce 60 parity-even independent geometrical couplings involving the B-field, metric, and d...
