CERN Physicists Measure Mass of Top Quark

Physicists from the CMS (Compact Muon Solenoid) Collaboration at CERN’s Large Hadron Collider (LHC) have considerably improved the precision with which the mass of the highest quark — the heaviest identified elementary particle – is measured. Their new end result (171.77 GeV) estimates the worth of the highest quark mass with a precision of about 0.22%. […]
