Résumé : We present a mechanism to generate complex phases from real [Formula Presented] dimensional couplings in a model of weak interactions through dimensional reduction of a gauge theory. The orbifolding of a [Formula Presented] dimensional [Formula Presented] group is the minimal setup which provides both [Formula Presented] violation and an [Formula Presented] structure. We show that grand unification requires at least [Formula Presented]. © 2004 The American Physical Society.
