Although this workshop is mainly concerned with the MeV to GeV scale,
new physics may hide at even lower perhaps sub-eV masses. A famous
example is the axion which has a sub-eV mass, solves the strong CP
problem (appearing at the few 100 MeV scale of QCD) and is also one of
the leading dark matter candidates.
Going beyond this example we argue that there exists an excellent
`physics...

A possible "Dark Boson" explanation for the 3.6sigma discrepancy between the muon anomalous magnetic moment theory and experiment is reviewed. Implications for low energy atomic and polarized electron scattering parity violation experiments are described. Signatures for such a "Dark Boson" in K, B and Higgs decays are discussed.

After a series of parity violating electron scattering experiments which explored the
strangeness content of the nucleon, we plan on a new, improved parity violation
experiment
where we will measure the weak charge of the proton with a
relative accuracy of 1.7%. This accuracy results in a measurement of the
effective electroweak mixing angle sin^2 theta_W of 1.5 per mille, which is an...

We study a possibility of neutral pion and dark photon production at a
high-luminosity photon-electron collider with the energy of the photon
about 20 Mev and the energy of the electron about 1 GeV.
The neutral pion production channel is Primakoff-type via the t-channel
photon exchange.
The dark photon production channel is similar to the timelike Compton
scattering on the...
