NEAR THRESHOLD η MESON PRODUCTION IN dp COLLISIONS
Abstract
Preliminary results of recent measurements of the near threshold η meson production in the dp → dpη reaction are presented. The experiment was performed at the COSY-Juelich accelerator with the use of the COSY-11 detection system. Data were taken for three values of deuteron beam momenta corresponding to excess energies of 3.2, 6.1 and 9.2 MeV. The energy dependence of the total cross section confirms a strong effect of the final state interaction.
