Description
The Deutsches Elektronen-Synchrotron DESY is Germany’s largest acceler-
ator laboratory, with programmes in particle physics, astroparticle physics and
photon science, and with R&D activities in the areas of accelerators, detectors
and computing. In particle physics, DESY is a key contributor to experiments
at the LHC and at the SuperKEKB collider. The laboratory hosts the ALPS II
experiment and plans to use the DESY infrastructure for hosting further axion
and strong-field QED experiments. DESY is home to a broad and world-class
theory group. The laboratory commands important system competences and
infrastructures, including a test beam facility that is used by hundreds of users
per year for particle physics experiments. DESY plays the important role of
a national hub and facilitator for large-scale German contributions to interna-
tional particle physics endeavours. The laboratory is also very visibly contrib-
uting to efforts for defining the next big collider project in the field. This paper
describes DESY’s current scientific programme as a whole, and it elaborates
on the strategy for the future development of particle physics at DESY.
