Feeble forces and gravity.
Abstract
We develop a scenario in which feeble intermediate range forces emerge as an effect resulting from the compactification (à la KaluzaKlein) of multidimensional theories. These feeble forces compete with gravity and in general permit different bodies to fall to earth with different accelerations. We show that these feeble forces are mediated by vectors (V) and/or scalars (S), whose dimensionless coupling constants are typically of order g_{v} ≈ g_{s} ≈ 10^{10} Under certain plausible assumptions the ranges of these feeble forces are expected to be of order 1 m to 1 km. It is conjectured that the general strategy will prove applicable to realistic multidimensional theories such as the 10dimensional superstring theories. We speculate that deviations from the standard gravitational forcesimilar to the ones reported recently as a “fifth force”may be interpreted as evidence for higher dimensions.
