L3 experiment at LPHE

L3 is an experiment designed to study electroweak interactions induced in electron-positron collisions at a center-of-mass energy of about 100 GeV (200 GeV to be achieved in the future) in the Large Electron-Positron collider (LEP) at CERN. About 500 physicists from 48 research institutions from 16 countries are collaborating on L3. The LPHE, a member of the collaboration from the start, contributed to the construction of the detector and now takes part in the data collection and analysis. This research has led to numerous publications and some LPHE PhD theses.

The main contribution of LPHE to the L3 detector is the electronic cooling system which has been developed and built in collaboration with CERN. This system has survived 15 years of work with only minor interventions. A paper describing the system in detail is in preparation.

At present (1998-1999) the analysis work done at LPHE are:
  • the study of B mesons excited states
  • the search of Flavour Changing Neutral Events (FCNC) in Z decay.

  • L3 publications
