The discovery of a Higgs boson at the Large Hadron Collider at CERN, announced on 4 July 2012, constitutes a major milestone for elementary particle physics. This boson could be the key to a long-standing question of the scientific world: the origin of mass itself.
Our CMS Higgs group at DESY has contributed importantly to the historic Higgs discovery paper of CMS, and is deeply involved in key research clarifying the nature and the properties of the observed Higgs itself, and the structure of a possible Higgs sector.
