Compact Muon Solenoid
{{main|Compact Muon Solenoid}}
One of the primary points of interest in the quiet community of Cessy, France
is the Compact Muon Solenoid (CMS) experiment, located 100 meters below ground
at a site on the south-eastern edge of the village. CMS is a high-energy particle physics experiment which observes the
result of high energy proton-proton collisions of the CERN laboratory's Large
Hadron Collider (LHC) particle accelerator.{{Cite web |url=http://cms.cern.ch/# |title=CMS home page |access-date=2010-05-25 |archive-url=http://wayback.vefsafn.is/wayback/20081115135747/http://cms.cern.ch/# |archive-date=2008-11-15 |url-status=dead }}
