CMS is a general purpose experiment, designed to study the physics of pp collisions at 14 TeV Large Hadron Collider (LHC). It currently involves more than 2000 physicists from 150 institutes and 37 countries. The LHC will provide extraordinary opportunities for particle based on its unprecedented collision energy luminosity when it begins operation in 2007.
