Unknown elementary particles can be searched for using atomic spectroscopy, with potentials resulting from pseudoscalar and pseudovector particles. Interaction constants of these potentials can be extracted from experimental spectra.
Hitherto unknown elementary particles can be searched for with atomic spectroscopy. We conduct such a search using a potential that results from the longitudinal polarization of a pseudovector particle. We show that such a potential, inversely proportional to the boson's mass squared, V proportional to 1/M-2, can stay finite at M -> 0 if the theory is renormalizable. We also look for a pseudoscalar boson, which induces a contact spin-dependent potential that does not contribute to new forces searched for in experiments with macroscopic objects, but may be seen in atomic spectroscopy. We extract limits on the interaction constants of these potentials from the experimental spectra of antiprotonic helium, muonium, positronium, helium, and hydrogen.
