Abstract

Dimensional reduction in Kaluza-Klein theories is discussed. In particular the one-loop contribution of an infinite tower of heavy Kaluza-Klein modes to a Green function and coupling constant renormalization are studied in the case of a scalar model on a six-dimensional spacetime with two dimensions being compactified to a torus. It is shown that the contribution of heavy modes decouples in the limit of zero size of the space of extra dimensions. A renormalization scheme with manifest decoupling of heavy masses is described, and interpolation of the renormalization group (RG) β-functions between various dimensions is discussed.
