Flavour violation with a single generation

Abstract

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 $\Delta G=0$, for instance $K\to {\mu }^{\pm }{e}^{\mp }$. The bound on the size of the extra dimensions is $1/R\gtrsim 64$ TeV.
