Precision Physics of Simple Atoms and Constraints on a Light Boson with Ultraweak Coupling
Abstract
Constraint on spin-dependent and spin-independent Yukawa potential at atomic scale is developed. That covers constraints on a coupling constant of an additional photon γ* and a pseudovector boson. The mass range considered is from 1eV/c2 to 1MeV/c2. The strongest constraint on a coupling constant α' is at the level of a few parts in 1013 (for γ*) and below one part in 1016 (for a pseudovector) corresponding to mass below 1keV/c2. The constraints are derived from low-energy tests of quantum electrodynamics and are based on spectroscopic data on light hydrogenlike atoms and experiments with magnetic moments of leptons and light nuclei.
