AbstractIt is shown that an anomalous energy-dependent modification of Newton's law could be obtained not only in a broken supersymmetry model of gravity, but also in the case of broken local Lorentz symmetry; in particular, the explicit expression for the radial acceleration of a test particle, in the field of a static central source, is derived in the framework of a quasi-riemannian geometric theory with SO(3) gauge invariance. It is then suggested that a measurement of the gravitational properties of relativistic microscopic matter and antimatter (whose importance has been recently stressed for quantum-gravity and supersymmetric models) could be interpreted also as a test on the eventual Lorentz noninvariance of high-energy gravitational dynamics.
