T-duality building blocks for αα' string corrections

By Marina David and James Liu
T-duality has been shown to constrain the higher derivative corrections of string theory. We revisit the problem of understanding the T-duality constraints imposed on the α\alpha' corrections using the language of a torsionful connection. We find a convenient way to express the O(d,d)O(d,d) invariants in terms of linear combinations of... Show more
