Compton photoproduction of axion-like, dark photon, dark scalar, and dark matter particles

Abstract:

We propose a novel way to search for the axion-like pseudo-scalar (a), the dark photon (A'), the dark scalar (*), and the light dark matter (*) in the Compton process,   * + e- *  a/A'/* + e- with a/A'/* decaying into leptons, photons, or *'s (when permitted) for the mass ranges of 1 [cid:image001.png at 01D5071F.3C7BE1F0]  mA'/a/* [cid:image002.png at 01D5071F.3C7BE1F0] 0 MeV/c2 and 0.5 [cid:image001.png at 01D5071F.3C7BE1F0]  m* [cid:image003.png at 01D5071F.3C7BE1F0] 50 MeV/c2, respectively. We will review how past, current, and future experiments (beam-dump and fixed target using a lepton or photon beam) can use this new production mechanism of dark particles. We will dis-cuss the expected sensitivities of these experiments on the axion-like pseudo-scalar coupling to electron (gae), the kinetic mixing (*) between the dark photon and the photon, and the dark scalar coupling to electron (ye).
