Completed Experiments

• Muonium-Antimuonium-Conversion
  A test of lepton flavour conservation.
  
  
• Large Acceptance Detector System (LADS)
  Investigation of the interaction of pions in nuclear matter.
  
  
• Search for Heavy Neutral Particle
  This experiment tests the claim by the Karmen collaboration of a heavy neutral particle.
  
  
• Muon-Electron Conversion
  A sensitive search for this process forbidden in the standard model.
  
  
• Improved Measurement of Charged Pion Mass
  Should help to improve the muon neutrino mass limit.
  
  
• Time Reversal Violation in Muon Decay?
  A search for time reversal vialation in muon decay and an improved measurement of various Michel parameters in order to look beyond the standard model.
  
  
• F/B Muon Spectrometer at L3
  W-boson Physics at LEP-2.
  
  
• Pion beta-decay
  An experiment to improve the accuracy of the CKM-matrix element V_ud
  
  
• Pionic Hydrogen
  Measures the pion-nucleon scattering length for a test of chiral pertubation theory.
  
  
• Central Silicon Tracker at H1
  Looking for displaced vertices at HERA.
