The CMS experiment

The Compact Muon Solenoid Experiment is one of the leading high energy physics experiments associated to the LHC (Large Hadron Collider), the highest energy proton-proton collider ever built at the European Laboratory for Particle Physics (CERN) located in Geneva (Switzerland). LHC started its operation in 2009, and it's expected to provide high energy collisions (up to 14 TeV in the center of mass) for about 10/15 more years.

CMS is composed of an international collaboration of above 3000 scientists from almost 200 different institutions. The aim of CMS is studying particle physics in the TeV range, providing precision measurements of the Standard Model and testing new models and theories. One of the most successful results up to date has been the discovery of the Higgs Boson.

CIEMAT participation in CMS

The CIEMAT High Energy Physics group joined this collaboration in the early stages of the experiment, and remained involved in several subprojects ever since. In particular the group took a leading role in the design and assembly of the central muon detector, in particular in the production of its fundamental component, the Drift Tube Chambers, and their readout electronics and the alignment system of these chambers with respect to the inner tracker. Almost 30 % of the drift tube chambers from the muon spectrometer were assembled in Madrid.

The group is also involved in the development of simulation and reconstruction software, as well as the Monte Carlo events production.

The CIEMAT CMS group has a strong participation in numerous topics regarding LHC data analysis, among them the study of electroweak interactions, the top quark, the Higgs boson and searches for physics beyond the Standard Model (Supersymmetry, excited leptons and many other exotic analyses).

Last but not least, the group is currently involved in the study and design of additional components for the DT detector that will be needed in the future for the operation of CMS under a higher luminosity regime. In particular the local electronics for readout and trigger will be redesigned and asssembled. Our group has a leading role in this upgrade operation.
