Title: Dark matter searches with long-lived particles

Abstract: Today's searches for dark matter suggest that it might interact only 

very weakly with the particles we observe. This insight changes our 
picture of how the dark matter abundance was created in the early 
universe. In this seminar, we will test this picture at the LHC. In a 
scenario with tiny couplings to the Higgs boson, I will show that dark 
matter is produced from long-lived particles that leave peculiar 
signatures in the LHC detectors. Their discovery can tell us more about 
the origin of the observed dark matter abundance.
