T-duality and α′-corrections
Abstract: We construct an O(d, d) invariant universal formulation of the first-order α′-corrections of the string effective actions involving the dilaton, metric and two-form fields. Two free parameters interpolate between four-derivative terms that are even and odd with respect to a Z2-parity trans...
