摘要

Physical effects in brane world models emerge by the incorporation of field modes coming from extra dimensions with the usual four-dimensional ones. Such effects can be tested with well-established experiments to set bounds on the parameters of the brane models. In this work we extend a previous result which gave finite electromagnetic potentials and self-energies for a source looking pointlike to an observer sitting in a 4D Minkowski subspace of a single brane of a Randall-Sundrum spacetime including compact dimensions, and along which the source stretches uniformly. We show that a scalar particle produces a nonsingular static potential, possesses a finite self-energy, and that technically its analysis is very similar to the electrostatic case. As for the latter, we use the deviations from the Coulomb potential to set bounds on the anti-deSitter radius of the brane model on the basis of two experiments, namely, one of the Cavendish type and the other being the scattering of electrons by helium atoms. We found these are less stringent than others previously obtained using the Lamb shift in hydrogen.
