Dark photon search at MAGIX — •Pepe Gülker for the MAGIX collaboration — JGU Mainz

The multi-purpose MAGIX experiment at the future electron accelerator MESA will be perfectly suited to extend the search for invisible dark photon decays to an unprecedented parameter range. We plan to perform scattering experiments on a windowless gas-jet target with low-energy electron probes delivered by MESA. They are produced in an energy-recovering acceleration mode, which yields a beam current of 1 mA. By this we will, in theory, be able to take data with very high accuracy.

To find suitable kinematics and get estimations for the sensitivity, a dedicated Monte-Carlo-simulation of the signal- and most relevant background-processes was performed and will be presented in this contribution.
