Simulated detection of Higgs boson. Computer simulation of an event in which the decay of a Higgs boson particle produces four muons (red tracks). The muons, along with countless other particles (blue tracks), are produced in a head-on collision between two protons. The Higgs boson is a localised clustering in the Higgs Field. This field permeates space, and local distortions of the Higgs Field are thought to be the way that particles gain mass. This image shows how the Higgs boson might be seen in the CMS detector on the Large Hadron Collider at CERN, the European particle physics laboratory.
