Abstract
We use the formalism of spin-1 (graviphoton) and spin-0 (graviscalar) partners of the graviton developed in this series to analyze four terrestrial experiments. This analysis is aided by the results of Stacey, Tuck, and Moore of Australian mine data, which allow interaction ranges up to 450 km. We find that an anomalous result of order 10% could occur for the gravitational acceleration of antimatter. Such ranges could also explain the apparently contradictory results of the Brookhaven and Washington Eötvös experiments in terms of the local geology. In the appendixes we rule out two other possibilities. The first would perform a gravity measurement inside a spherical shell: a ‘‘Gauss’s law’’ test. The second would be a new rotating-disk Cavendish experiment.
