A large, precise set of polarization observables for deuteron-proton breakup at 130 MeV.

High precision vector A_x,A_y and tensor A_xx,A_xy,A_yy analyzing powers for the ¹H(dvector ,pp)n breakup reaction were measured at 130 MeV beam energy with the detection system covering a large part of the phase space. Results are compared with rigorous theoretical calculations based on realistic nucleon-nucleon potentials, also with a so-called three-nucleon force included, as well as on chiral perturbation theory. Theoretical predictions generally describe the data quite well, but in some regions discrepancies have been observed, which indicate incompleteness of the present-day treatment of three nucleon dynamics.
