SPIN OBSERVABLES OF THE DEUTERON BREAKUP REACTION pd -> pp(1S0)n AND SHORT-RANGE NN PROPERTIES

Uzikov Yu. N., Seyfarth H.

Analysis of recent ANKE-COSY data on the deuteron breakup pd -> pp(1S0)n in a kinematics similar to backward pd elastic scattering shows very high sensitivity of this process to the short-range NN interaction. Employing the CD Bonn potential instead of the RSC or Paris potentials changes all contributions of the deuteron breakup model based on the one-nucleon exchange, single pN scattering and D excitation mechanism in the right direction and achieves good qualitative agreement with the measured unpolarized cross section. Spin observables, planned to be measured at ANKE-COSY, are calculated here within the above model.
