As a high intensity and high beam quality electron accelerator, the Mainz Microtron (MAMI) is well suited for the search for possible gauge bosons of the dark sector, the so called dark photons. The capabilities of the accelerator in combination with the high resolution spectrometer setup of the A1 collaboration were already demonstrated in a first test experiment in 2011. An extension of this...

9. Light Dark Gauge Boson Searches in Electron-Proton Scattering: Description of Present Data and Simulation for Future Experiments

We study the exploration reach of various fixed target experiments searching for the dark photon. Therefore we investigate the creation of a lepton pair induced by quasi elastic scattering of an electron beam off a heavy nucleus (A,Z), i.e. e(A,Z) -> e (A,Z) e^+e^- with a dark photon A' as signal and a virtual photon as background in the intermediate state. We present our calculations in...

40. Hidden Photons in beam dump experiments

Recently there has been much interest in hidden sectors with light extra U(1) gauge bosons, so called hidden photons. On the theoretical side, scenarios of that kind are well motivated as a common feature of physics beyond the Standard Model like string theory and SUSY. Because of their possible connection with dark matter they received further attention also from a phenomenological point of...
