Discovery of the Weak Neutral Current

Discovery of the Weak Neutral Current
- Summer 1973 (Gargamelle, CERN)
- SM predicted: nmN ® nmX
First Generation EW Experiments
- Experiments in the late 1970’s
- Precision at the 10% level
- Tested basic structure of SM Þ MW,MZ
Second Generation EW Experiments
- Experiments in the late 1980’s
- Discovery of W,Z boson in 1982-83
- Precision at the 1-5% level
- Radiative corrections become important
- First limits on the Mtop
Third Generations Experiments
- Precision below 1% level
- Test consistency of SM
- Search for new physics and
- Constrain MHiggs
- Þ Predict light Higgs boson
- (and possibly SUSY)
