ALEPHThe ALEPH experiment explored the high energy frontier of electron-positron collisions. It was based at the LEP storage ring at the CERN laboratory in Geneva, Switzerland. Electrons were collided against positrons at up to 209 GeV in the centre of mass. This energy was sufficient to produce pairs of W and Z gauge bosons (the carriers of the weak force), and to make precision measurements of their properties. It was also used to set direct limits on the Higgs boson mass (m_H > 114 GeV).

The Glasgow group's interests were in the fields of b physics (where we studied decays of interest for evidence of CP violation), and the search for the Higgs boson (see the Theses links for additional information). These interests continue with the LHCb and ATLAS experiments at the LHC.

The ALEPH experiment finished data-taking on November 2, 2001.
