Abstract

As known, electron vacuum polarization by nuclear Coulomb field produces Uehling potential with the range /2mec\hbar/2m_e c. Similarly, neutrino vacuum polarization by ZZ boson field produces long range potential GF2/r5\sim G_F^2/r^5 with a very large range /2mνc\hbar/2m_{\nu}c. Measurements of macroscopic effects produced by potential Geff2/r5G_{\rm{eff}}^2/r^5 give limits on the effective interaction constant GeffG_{\rm{eff}} which exceed Fermi constant GFG_F by many orders of magnitude, while limits from spectroscopy of simple atomic systems are approaching the Standard Model predictions. In the present paper we consider limits on GeffG_{\rm{eff}} from hydrogen, muonium, positronium, deuteron, and molecular hydrogen. Constraints are also obtained on fifth force parameterised by Yukawa-type potential mediated by a scalar particle.
