Résumé : We calculate probabilities of flavour violating processes mediated by Kalutza-Klein modes of gauge bosons in a model where three generations of the Standard Model fermions arise from a single generation in (5+1) dimensions. We discuss a distinctive feature of the model: while the processes in which the generation number G changes are strongly suppressed, the model is constrained by those with ΔG = 0, for instance K → μ±e ∓. The bound on the size of the extra dimensions is 1/R ≳ 64TeV. © SISSA/ISAS 2004.
