This track is an example of simulated data modelled for the ATLAS detector. The Higgs boson is produced in the collision of two protons at 14 TeV and quickly decays into four muons, a type of heavy electron that is not absorbed by the detector. The tracks of the muons are shown in yellow.
CMS weighs more than 12,000 tons.
Scientists on the accelerator's LHCb (or LHC Beauty) experiment stand in front of their detector, which searches for rare particle decay processes.

The ring of the LHC extends 17 miles (27 kilometers) underneath Switzerland and France.
LHC first fired up in 2008, but went offline shortly thereafter when some of its giant magnets failed because of faulty connections.

The LHC experiments include thousands of physicists from dozens of countries.
LHC's ALICE Experiment
The ALICE experiment at the Large Hadron Collider studies heavy-ion collisions in search of a quark-gluon soup similar to the state of the early universe.
