The Low Side of the Dark Side

The quest for the particle nature of Dark Matter is one of the big open questions of modern physics.
A well-motivated candidate for Dark Matter is the so-called WIMP - a weakly interactive massive particle.
Recently several theoretically well-motivated models with Dark Matter candidates in a mass region below
the WIMP mass-scale gained also a lot of interest, theoretically and experimentally. The CRESST II experiment
located at the Gran Sasso laboratory in Italy is optimised for the detection of the elastic scattering of these low mass
Dark Matter particles with nuclei. Besides the search for Dark Matter particles scattering with nuclei, we present a new
search for so-called Dark Photons, also based on CRESST data. Finally the potential and the layout of a future silicon
based dark matter experiment, dedicated to sub-GeV Dark Matter detection, is discussed.
