Editing Compact Muon Solenoid (section)

==Background==
Recent collider experiments such as the now-dismantled [[LEP|Large Electron-Positron Collider]] and the newly renovated [[Large Hadron Collider]] (LHC) at CERN, as well as the ({{As of|October 2011|lc=on}}) recently closed [[Tevatron]] at [[Fermilab]] have provided remarkable insights into, and precision tests of, the [[Standard Model]] of Particle Physics. A principal achievement of these experiments (specifically of the LHC) is the discovery of a particle consistent with the Standard Model [[Higgs boson]], the particle resulting from the [[Higgs mechanism]], which provides an explanation for the masses of elementary particles.<ref>{{cite web|title=The Higgs Boson|url=http://home.web.cern.ch/topics/higgs-boson|website=CERN: Accelerating Science|publisher=CERN|access-date=11 June 2015}}</ref>

However, there are still many questions that future collider experiments hope to answer.  These include uncertainties in the mathematical behaviour of the Standard Model at high energies, tests of proposed theories of [[dark matter]] (including [[supersymmetry]]), and the reasons for the [[CP Violation|imbalance]] of matter and antimatter observed in the Universe.
