When this happens some of the energy of the collision is turned into mass and previously unobserved, short-lived particles – which could give clues about how Nature behaves at a fundamental level - fly out and into the detector.ĬMS is a particle detector that is designed to see a wide range of particles and phenomena produced in high-energy collisions in the LHC. Many of these will just be glancing blows but some will be head on collisions and very energetic. The LHC smashes groups of protons together at close to the speed of light: 40 million times per second and with seven times the energy of the most powerful accelerators built up to now.

This will help us answer questions such as: 'what is the Universe really made of and what forces act within it?' and 'what gives everything substance?' Such research increases our basic understanding and may also spark new technologies that change the world we live in. CMS data is analyzed by scientists around the world to build up a picture of what happened at the heart of the collision. Some of the collision energy is turned into mass, creating new particles which are observed in the Compact Muon Solenoid (CMS) particle detector. The Large Hadron Collider (LHC) at CERN smashes protons together at close to the speed of light with seven times the energy of the most powerful accelerators built up to now.
