On the KaluzaKlein vacuum
Abstract
It is argued by an explicit model that a quantum KaluzaKlein theory is insensitive enough to the choice of the ground state. In fact we show that any vacuum of the form M^{4+n} that be related to the standard one M^{4} × B^{n} by gaussian random fluctuations, gives the same 1PIgenerating functional of the quantum KaluzaKlein theory based on M^{4} × B^{n}.
