We acknowledge the outstanding work of the RIKEN Accelerator group for delivering excellent polarized deuteron beams. We thank P. U. Sauer and A. Deltuva for providing their results as shown in this paper and for their useful comments. K.S. would like to acknowledge the support of the Special Postdoctoral Researchers Program of RIKEN. N.K. and K.E. would like to thank RIKEN for the hospitality during their stay in Japan. This work was supported financially in part by the Grants-in-Aid for Scientific Research Numbers 04402004 and 10304018 of the Ministry of Education, Culture, Sports, Science, and Technology of Japan, the Polish Committee for Scientific Research under Grant No. 2P03B00825, and DOE Grants No. DE-FG03-00ER41132 and No. DE-FC02-01ER41187. The numerical calculations were performed on the SV1 and the CRAY T3E of the NIC in Jülich, Germany.

N2 - The deuteron-to-proton polarization-transfer coefficients for d-p elastic scattering were precisely measured with an incoming deuteron energy of 135 MeV/nucleon at the RIKEN Accelerator Research Facility. The data are compared to theoretical predictions based on exact solutions of the three-nucleon Faddeev equations with high-precision nucleon-nucleon forces combined with the current, most popular three-nucleon force (3NF) models: the 2π-exchange Tucson-Melbourne model, a modification thereof based on chiral symmetry, TM'(99), and the Urbana IX 3NF. Theory predicts large 3NF effects, especially in the angular range around the cross section minimum, predominantly for K xxy′-Kyyy′ (K xxy′,Kyyy′), but the present data only partially concurs with the calculations. For the induced polarization, Py′, the TM′(99) and Urbana IX 3NFs reproduce the data, but the Tucson-Melbourne 3NF fails to describe the data. For the polarization-transfer coefficients, Kyy′ and Kxzy′, the predicted 3NF effects are in drastic disagreement with the data. These facts clearly reveal the defects of the 3NF models currently used.
