The Muonium Atom as a Probe of Physics beyond the Standard Model

The observed interactions between particles are not fully explained in the successful theoretical description of the standard model to date. Due to the close confinement of the bound state muonium ($M = \mu^+ e^-$) can be used as an ideal probe of quantum electrodynamics and weak interaction and also for a search for additional interactions between leptons. Of special interest is the lepton number violating process of sponteanous conversion of muonium to antimuonium.Comment: 15 pages,6 figure

LIQUID-XENON-FILLED WIRE CHAMBERS

The authors describe several types of small liquid xenon-filled chambers, each optimized for a particular property such as a real-time spatial resolution of {+-} 15 {mu}, a time resolution of {+-} 10{sup -7} sec, or a pulse height of 10{sup -12} coulomb. Larger chambers combining all these properties will be of great value at NAL energies, and they describe some of the techniques necessary for their construction
