DESY is one of the world’s leading centres in particle physics and has phased out the operation of its own large-scale facilities in this programme. In the coming programme period, DESY will focus on the following projects, thereby securing the institute’s and Germany’s leading role in particle physics:

• Substantial participation in two LHC experiments (ATLAS and CMS). At the same time, the precision analyses of the HERA experiments will be completed. Its results are also of great importance for the LHC analyses.
• Further expansion of the Grid Computing Centre Karlsruhe (GridKa) at KIT as well as the Tier2-Centres and the analysis centre at DESY.
• Theoretical studies in close connection with the experimental activities as well as research at the interface between particle/astroparticle physics and string theory. The lattice gauge theory, including research and development for novel processors, will be continued at the DESY site in Zeuthen in close collaboration with the John von Neumann Institute of the Forschungszentrum Jülich.
• Collaboration in the continuing development of superconducting accelerator technology for the International Linear Collider (ILC), in which DESY plays a world-leading role. Use of the synergy between XFEL and the ILC.
• Detector development for the luminosity increase of the LHC and for precision experiments at the ILC, contributions to the development of detectors for XFEL.
• The Helmholtz Alliance “Physics at the Terascale” is to be consolidated as a result of the review.
