The CMS Experiment at LHC

The Cms Collaboration Has Observed A New Production

Mechanism Of Top Quarks

A candidate collision from the LHC in which a top quark is produced in association with a Z boson. The tZq state is characterised by three leptons (in this case two electrons and one muon), a jet produced from decay of a bottom quark, and a forward jet that is close to the LHC beam direction.

A 100 metres underground, cathedral-sized cavern that houses the 14 000-tonne CMS detector - one of the two experiments that discovered the Higgs boson! The detector is located in the 27-km subterranean tunnel that contains the LHC - the world's largest scientific instrument!
