Resumo: In this talk I will describe the relation between Riemannian submersions and Kaluza-Klein models on higher-dimensional spacetimes M4 ×K. The setting will be slightly more general than usual, as we consider submersions whose fibres need not be totally geodesic. In these conditions, the higher-dimensional metric encodes both massless and massive 4D gauge fields, as well as a non-trivial Higgs sector. I will discuss some of the new features that appear in these models.
