Measurement of the vector and tensor analyzing powers for dp-elastic scattering at 880 MeV

The vector Ay and tensor analyzing powers Ayy and Axx for dp-elastic scattering were measured at Tdlab=880 MeV over the c.m. angular range from 60° to 140° at the JINR Nuclotron. The data are compared with predictions of different theoretical models based on the use of nucleon-nucleon forces only. The observed discrepancies of the measured analyzing powers from the calculations require the consideration of additional mechanisms.
