\(p\bar p\) Annihilations at Rest in Hydrogen Gas: Report on Preliminary Results of the Asterix Experiment at Lear
The ASTERIX experiment has been set up to study \(p\bar p\)-annihilations at rest into \(q\bar q\)-mesons and other boson resonances like glueballs (gg, ggg), hybrids (\(q\bar qq\)), baryonia (\(qq\bar q\bar q\)) and \(N\bar N\) bound states from S and P states of the \(p\bar p\) atom. A detailed description of the apparatus can be found in the proposal1) and in the contributions to the LEAR Erice Workshop 19822, 3)
