The W and Z particles were first observed at CERN 20 years ago by the UA1 and UA2 experiments. Daniel Denegri, who worked with UA1, recollects the spirit of discovery at the time.
The measurements gave a value for an electroweak parameter that was three standard deviations higher than predicted by the Standard Model.
CERN's LEP electron-positron collider closed last year after a tantalizing and controversial finish, which revealed hints of the long-awaited Higgs particle - the missing link in today's picture of p...
CERN's LEP electron-positron collider stubbornly refused to lie down quietly in 2000.
With possible signs of the elusive Higgs particle on the horizon, on 14 September CERN decided to
extend the life of its flagship LEP electron-positron collider until 2 November 2000.
After commencing 2000 operations in fine style, CERN's flagship machine, the LEP electron-positron collider, has been regularly delivering experiments with beams of 103 GeV or more.
A quarter of a century ago, Martin Perl discovered a new particle: the tau lepton. This weakly interacting particle is so heavy that it can decay into strongly interacting particles and provide very ...
While we wait for a definitive sighting of the enigmatic Higgs particle, there is no lack of careful precision work for the experiments at CERN's LEP electronpositron collider. Bob Clare of MIT look...
Some of the most compelling questions in particle physics today are to do with the Higgs boson and supersymmetry (SUSY).
