Abstract: The proton to proton polarization transfer coefficients K-x(x'),K-y(y'), and K-z(x'), and the proton to deuteron polarization transfer coefficients K-x(x'),K-y(y'),K-z(x'), K(x)(y')z('),K(y)(z')z('),K(z)(y')z('),K(y)(x')z('), and K(y)(x')x(')-y(')y(') were measured in d(p,p)d and d(p,d)p reactions, respectively, at E-p(lab)=22.7 MeV. The data were compared to predictions of modern nuclear forces obtained by solving the three-nucleon Faddeev equations in momentum space. Realistic (semi)phenomenological nucleon-nucleon potentials combined with model three-nucleon forces and modern chiral nuclear forces were used. The AV18, CD Bonn, and Nijm I and II nucleon-nucleon interactions were applied alone or combined with the Tucson-Melbourne 99 three-nucleon force, adjusted separately for each potential to reproduce the triton binding energy. For the AV18 potential, the Urbana IX three-nucleon force was also used. In addition, chiral NN potentials in the next-to-leading order and chiral two- and three-nucleon forces in the next-to-next-to-leading order were applied. Only when three-nucleon forces are included does a satisfactory description of all data result. For the chiral approach, the restriction to the forces in the next-to-leading order is insufficient. Only when going over to the next-to-next-to-leading order does one get a satisfactory description of the data, similar to the one obtained with the (semi)phenomenological forces.
