We consider the Calabi-Yau reduction of the Type IIA eight derivative oneloop stringy corrections focusing on the couplings of the four dimensional gravity multiplet with vector multiplets and a tensor multiplet containing the NS two-form. We obtain a variety of higher derivative invariants generalising the one-loop topological string coupling, F1, controlled by the lowest order Kähler potential and two new non-topological quantities built out of the Calabi-Yau Riemann curvature.

Abstract
We consider the Calabi-Yau reduction of the Type IIA eight derivative oneloop stringy corrections focusing on the couplings of the four dimensional gravity multiplet with vector multiplets and a tensor multiplet containing the NS two-form. We obtain a variety of higher derivative invariants generalising the one-loop topological string coupling, F1, controlled by the lowest order Kähler potential and two new non-topological quantities built out of the Calabi-Yau Riemann curvature.
