We study loop corrections to the universal dilaton supermultiplet for type IIA strings compactified on Calabi-Yau threefolds. We show that the corresponding quaternionic kinetic terms receive non-trivial one-loop contributions proportional to the Euler number of the Calabi-Yau manifold, while the higher-loop corrections can be absorbed by field ��

String loop corrections to Kähler potentials in orientifolds (2005, background): “A similar kind of mixing between geometric and non-geometric scalar fields in the definition of the appropriate Kähler variables is familiar from other circumstances, like from compactifications of the heterotic string (see for instance [17]) or from N = 2 compactifications of type-II theories [18].”

D-instantons and twistors (2008, unknown): “Arguments for the absence of perturbative corrections beyond oneloop were given in [27, 30, 31].”
String loop corrected hypermultiplet moduli spaces (2006, methodology): “Here, φ is related to the four-dimensional dilaton in a way explained in [19], and the oneloop constant χ1 is proportional to the Euler number χ = 2(h 1,1 − h(1,2)) of the CY3.”
