Near Threshold Η Meson Production in Dp Collisions

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… CONTINUE READING
