Title: Corrections to the Newton and Coulomb potentials caused by effects of spacetime foam

Item Type: Journal Article
Abstract: We use an extended quantum field theory (EQFT) hep-th/9911168 to explore possible observational effects of the spacetime. It is shown that as it was expected the spacetime foam can provide quantum bose fields with a cutoff at very small scales, if the energy of zero - point fluctuations of fields is taken into account. It is also shown that EQFT changes the behaviour of massless fields at very large scales (in the classical region). We show that as $rgg 1/mu $ the Coulomb and Newton forces acquire the behaviour $sim 1/r$ (instead of $1/r^{2}$).
