* Title : On the vacuum structure of F-theory compactifications
* Abstract : We study moduli stabilization of F-theory compactified on an elliptically fibered Calabi-Yau fourfold arising from open mirrorsymmetry prescription including the brane deformation. We focus on a particular background and utilize associated fourfold periods to determine the properties of resulting 4D N = 1 effective theory for moduli fields. It is found that the F-theory vacua have a remarkable structure even before taking into account the Kaehler moduli stabilization. Finally, we discuss the axion-induced baryogenesis scenario induced by the axion-dependent Yukawa couplings.
