I started thinking about wether it is possible to generate interaction in an effective field theory, when one assumes to have a free one in a space with additional higher, compactified dimensions through integrating out the contributions in the compactified dimension in the path integral or through some process of not lookin at the excitations in the additional dimension. Does anybody know wether this case is already looked at in the literature? René. |
