[Particle physics]

Research in basic particle and nuclear physics by the UCLA Particle Physics Research Group is reported in the following areas: rare decays of η and μ to test charge conjugation invariance, QCD, and the Standard Model; tests of charge symmetry and isospin invariance; studies of baryon resonances: πN scattering, inverse pion photoproduction, eta-meson photoproduction, and the production of the eta meson in π-p→ηn; and exploratory investigations in support of new programs (feasibility study of tagged eta meson production in p+3H→4He+η, the alternative η production reaction π+→p+p+η, particle physics with PILAC, quark physics at a phi-meson factory)
