The research training group joins members from experiment, theory and phenomenology of particle physics related institutes of Heidelberg University and the Max Planck Institute for Nuclear Physics (MPIK). Close collaboration with the Large Hadron Collider will be established through the LHCb and ATLAS experiments. Moreover, we are in contact with the Mu3e experiment planned at the Paul Scherrer Institute (PSI) in Switzerland. A detailed list of research groups provides the subsection supervisors. In addition we present our students which are integrated into the Heidelberg Graduate School of Fundamental Physics. Moreover, there is a list of alumni.
