The compact muon solenoid (CMS) detector in the large hadron collider (LHC)

The compact muon solenoid detector is one of the four experiments on the Large Hadron Collider at CERN. It was conceived to study proton-proton collisions at a centre-of-mass energy of 14 TeV and at luminosities up to 1034 cm-2s-1. The detector is characterized by its high ompactness, with the muon chamber encompassing almost the entire 4π solid angle. A high-field superconducting solenoid surrounds a silicon tracker, an electromagnetic calorimeter, and a hadron calorimeter. The resolution is excellent for detecting processes which involve electrons, photons and especially muons in the final state.
