Achim Stahl

Prof. Achim Stahl serves as University Professor and Chair at RWTH Aachen University, where he directs JARA-FAME (Jülich Aachen Research Alliance - Fundamental Forces and Particle Physics) and leads the 3rd Physics Institute B with approximately 70 scientists, engineers, and administrators. His research spans multiple domains of particle physics and experimental physics with significant contributions to major international collaborations including CMS at CERN, JUNO, Double Chooz, and the Einstein Telescope project.

• PhD in Physics from University of Heidelberg (1993), thesis: 'Installation, optimization and analysis of the ALEPH event trigger and investigation of muonic decays of tau leptons'
• Diploma in Physics from University of Tübingen (1988) with optimal mark 1.0
• Habilitation with book 'Physics with tau leptons' published in Springer Tracts in Modern Physics

Prof. Stahl's research spans multiple frontiers of particle physics. His primary interests include neutrino physics (mass hierarchy and CP-violation with experiments like JUNO, T2K, and Double Chooz), gravitational wave detection with the Einstein Telescope project, CP-violation studies through electric dipole moment searches, CMS experiment data analysis with tau leptons, and medical physics applications including radiation therapy and GEANT4 simulations. He has extensive hardware experience in detector development, including trigger systems, PMT readout, calorimeters, and position sensors.

His recent publications demonstrate expertise across diverse areas of particle physics, with significant contributions to Higgs boson physics, neutrino oscillations, CP violation studies, and detector development. A substantial portion of his work focuses on the CMS experiment at CERN and the JUNO neutrino experiment, reflecting his leadership in these major international collaborations. His publications show equal strength in theoretical analysis and experimental hardware development, particularly in trigger electronics and precision measurement systems.

While specific awards aren't detailed in the available information, Prof. Stahl has achieved an h-index of 120, reflecting significant impact in his field. His leadership roles include membership on the executive board of JUNO and serving as speaker of the DFG research unit FOR 2319 'Bestimmung der Massenhierarchie mit dem JUNO-Experiment'.

Prof. Stahl has supervised numerous students throughout his career, including 20 theses that led to 11 OPAL papers during his time at the University of Bonn. He coordinates national activities on the Einstein Telescope and is deeply involved in multiple neutrino projects. His research is supported by significant grants enabling participation in international collaborations and hardware development for major experiments. His team has developed innovative detector technologies including integrated PMT readout systems and trigger electronics for neutrino experiments.

As director of the 3rd Physics Institute B at RWTH Aachen, Prof. Stahl leads a substantial research group focused on fundamental physics questions. He is a founding member and current director of the JARA section FAME, which focuses on CP-violation and the matter-antimatter asymmetry in the universe. His team is actively developing technologies for the Einstein Telescope project, contributing to the JUNO neutrino experiment, conducting research with the CMS experiment at CERN, and applying particle physics techniques to medical applications.
