On four-derivative terms in IIB Calabi-Yau orientifold reductions

On four-derivative terms in IIB Calabi-Yau orientifold reductions

Abstract We perform a Kaluza-Klein reduction of IIB supergravity including purely gravitational α′3-corrections on a Calabi-Yau threefold, and perform the orientifold projection accounting for the presence of O3/O7-planes. We consider infinitesimal Kähler deformations of the Calabi-Yau background an...
