Yukawa Hierarchies from Split Fermions in Extra Dimensions
Eugene A. Mirabelli, Martin Schmaltz
Abstract
We explore a mechanism for generating the Yukawa hierarchies by displacing the left- and right-handed components of the Standard Model fermions in a higher-dimensional space. We find a unique configuration of displacements which fits all quark and lepton masses and mixing angles, with a prediction for the strange quark mass ms = 120 MeV.
