Abstract

We discuss CP violation in the quark sector within a novel approach to the Yukawa puzzle proposed by Arkani-Hamed and Schmaltz, where Yukawa hierarchies result from localising the Standard Model quark field wave-functions, at different positions (in the extra dimensions) in a ``fat-brane.'' We show that at least two extra dimensions are necessary in order to obtain sufficient CP violation while reproducing the correct quark mass spectrum and mixing angles.
