Astroparticle physics

Astroparticle physics is a rapidly developing field that has a high degree of overlap with particle physics and astronomy. This paper summarizes recent results and leading experiments in two selected areas: very high energy astrophysics and dark matter. Both areas have made great progress in the last 5 years due to improved instrumentation and a growing community. In very high energy astrophysics, many sources of GeV and TeV radiation have been detected and the challenge now is to fully understand the processes involved at these sites of extreme particle acceleration. In the area of dark matter, there is a close scientific connection between astroparticle experiments and the Large Hadron Collider (LHC). The combination of the LHC, direct-detection and indirect-detection experiments provide critical complementarity and unprecedented sensitivity in the quest to understand this deep mystery. (paper)
