Abstract
We consider N=1 F-theory and Type IIB orientifold compactifications and derive new \alpha' corrections to the four-dimensional effective action. They originate from higher derivative corrections to eleven-dimensional supergravity and survive the M-theory to F-theory limit. We find a correction to the Kahler moduli depending on a non-trivial intersection curve of seven-branes. We also analyze a four-dimensional higher curvature correction.

8 pages, revtex, v4: major revision. The reduction of recently found higher curvature terms showed that the previously presented Ansatz for the Kahler coordinates was not general enough. Details of the reduction appear in a follow-up work
