Simulation studies for the MADMAX Axion direct detection experiment — •Jan Schütte-Engel for the MADMAX collaboration — University Hamburg, Deutschland

Axions are hypothetical particles introduced to solve the strong CP problem of the Standard Model. In addition axions can resolve the dark matter mystery. Axions with masses in the range of a few µeV up to a few hundreds of µeV are furthermore motivated by the scenario in which the Peccei-Quinn symmetry is broken after inflation, and in which the vacuum realignment mechanism and decays of topological defects contribute to the dark matter density. These motivate the search for axions in direct detection experiments on Earth, and the development of new techniques to become sensitive to this specific axion mass region.

One option is the MADMAX experiment, a haloscope utilizing dielectric media to enhance the signal of photons converted axions. This talk will focus on the simulation of the MADMAX direct detection axion experiment, and especially on the investigation of the dielectric discs, including real experimental conditions and discussing some of the signal loss mechanisms which may impair the axion detection.
