That covers constraints on a coupling constant of an additional photon $\\gamma^*$ and a pseudovector boson. The mass range considered is from $1\\;{\\rm eV}/c^2$ to $1\\;{\\rm MeV}/c^2$. The strongest constraint on a coupling constant $\\alpha^\\prime$ is at the level of a few parts in $10^{13}$ (for $\\gamma^*$) and below one part in $10^{16}$ (for a pseudovector) corresponding to mass below $1\\;{\\rm keV}/c^2$.
