ω MESON PRODUCTION IN PROTON-PROTON COLLISIONS
International Journal of Modern Physics A(2007)
摘要
One of the experimental programs at the TOF spectrometer located at the COSY-accelerator (Forschungszentrum Jülich, Germany) is the study of ω-meson production in proton proton collisions (pp → ppω). Recently, a measurement was performed with a polarized beam at an excess energy of ∊ = 129 MeV , which offers the possibility to analyze polarization observables of this reaction channel for the first time. The analyzing power (Ay) of the pp → ppω-reaction was determined to be compatible with zero.
