Abstract

In this paper, based on the theory of parametric resonance, we propose a cosmological criterion of ways of compactification: we rule our such a modelof compactification in which there exists a Kaluza-Klein mode satisfying 2m(KK)= omega (b), where m(KK); is mass of the Kaluza-Klein mode and omega (b) is the frequency of oscillation of the radius of the compact manifold onwhich extra dimensions are compactified. This is a restatement of the criterion proposed previously [S. Mukohyama, Phys. Rev. D 57, 6191 (1998)]. As an example, we consider a model of compactification by a sphere and investigate Kaluza-Klein modes of a U(1) field. In this case the parametric resonance is so mild that the sphere model is not ruled out.
