摘要：

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 tin 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.
