It has been recently suggested by Dvali and Vikman that the superluminal neutrino phenomenology of the OPERA experiment may be due to an environmental feature of the Earth, naturally yielding a long-range fifth force of gravitational origin whose coupling with the neutrino is set by the scale M*, in units of reduced Planck mass. Its characteristic length λ should not be smaller than one Earth’s radius Re, while its upper bound is expected to be slightly smaller than the Earth-Moon distance (60 Re). We analytically work out some orbital effects of a Yukawa-type fifth force for a test particle moving in the modified field of a central body. Our results are quite general since they are not restricted to any particular size of λ; moreover, they are valid for an arbitrary orbital configuration of the particle, i.e. for any value of its eccentricity e. We find that the dimensionless strength coupling parameter α is constrained to |α| ≲ 1 × 10−10 − 4 × 10−9 for 1 Re ≤ λ ≤ 10 Re by the laser data of the Earth’s artificial satellite LAGEOS II, corresponding to M* ≳ 4 × 109 − 1.6 × 1010. The Moon perigee allows to obtain |α| ≲ 3 × 10−11 for the Earth-Moon pair in the range 15 Re ≲ λ ≲ 60 Re, which translates as M* ≳ 3 × 1010 − 4.5 × 1010. Our results are neither necessarily limited to the superluminal OPERA scenario nor to the Dvali-Vikman model, in which it is M* ~ 10−6 at λ ~ 1 Re, in contrast with our bounds: they generally extend to any theoretical scenario implying a fifth-force of Yukawa-type.
