Constraints on a vector coupling to baryon number from the Eötvös experiment
Abstract
We point out that the deviations Δκ in the Eötvös experiment do not correlate with the lepton and the neutron number of the used materials. As a consequence of these facts if the hypothetical ``fifth force'' is associated with a new U(1) gauge symmetry there must be new fermions in the extended model or this symmetry does not respect the family structure of the low-energy fermions.
