Combining Universal and Odd RR Axions for Aligned Natural Inflation
Abstract
We successfully embed the Kim-Nilles-Peloso (KNP) alignment mechanism for enhancing the axion decay constant in the context of large volume type IIB orientifolds. The flat direction is generated in the plane of (C0-C2) axions corresponding to the involutively even universal axion C0 and odd axion C2, respectively. The moduli stabilization with large volume scheme has been established as well.
