HERA Symposium 2027

In 1992, the so far only lepton-hadron collider started operation at DESY (Hamburg, Germany) and ran until 30th of June 2007. In total four experiments took data either in collider mode (H1 and ZEUS) or in a fixed-target setup (HERA-B and HERMES). The HERA Symposium 2027 will bring together that community, celebrating the achievements of this unique machine, reflecting on the periods of data taking and the harvesting after the shutdown of HERA and the experiments, as well as on the impact on the activities at the various worldwide laboratories.
