CMS Experiment at the CERN Large Hadron Collider
- Drawing of the CMS Detector
Particle Physics explores the fundamental structure of matter, space-time and the forces in our universe. Despite the enormous progress over the last century, important open questions remain unanswered today.
The CMS experiment at the new Large Hadron Collider at CERN was built to answer some of them, in particular to find the origin of mass and electroweak symmetry breaking as well as to search for the yet unexplored physics beyond the standard model. This is made possible by the 14 TeV collision energy of protons in the LHC, which is an order of magnitute higher than in the most powerful machine so far, the Tevatron. CMS is a multi-purpose detector which can explore whatever physics will be found out there at the "terascale".
Our institute is actively involved in the CMS Collaboration with contributions to detector development and construction as well as data reconstruction and analysis.
- CMS tracker end cap.
We have played a leading role in the construction of the CMS tracker, the largest silicon strip detector ever built. The tracker endcaps with their sub-structures have been developed by our group and have been build in a world-wide effort involving research groups from Europe and the USA. One complete endcap, shown in the picture to the right, was integrated in the clean rooms of our institute.
The laser alignment system for the CMS tracker was developed and built in our institute. In addition we work on the track based alignment of the CMS tracker.
Our physics data analyses focus on searches for the Higgs boson and for supersymmetric particles.
With the upgrade of the LHC to a yet more powerful machine on the horizon we have started research and development for a CMS tracker at the "SuperLHC".
Our participation in CMS is a common project of the groups of Prof. Feld and Prof. Schael. More information can be found following these links.
