Abstract
We consider five-dimensional SU(5) GUT models based on the orbifold S 1/(Z2 × Z′2), and study the different possibilities of placing the SU(5) matter multiplets in three possible locations, namely, the two branes at the two orbifold fixed points and SU(5) bulk. We demonstrate that if flavour hierarchies originate solely from geometrical suppressions due to wave function normalization of fields propagating in the bulk, then it is not possible to satisfy even the gross qualitative behaviour of the CKM and MNS matrices regardless of where we place the matter multiplets. © 2006 IOP Publishing Ltd.
